Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Horsehead Holding Corp. and its subsidiaries as of September 30, 2015 and for the three and nine months ended September 30, 2015 and 2014 have been prepared pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2015 . The accompanying financial statements include the accounts of Horsehead Holding Corp. and all of its subsidiaries (collectively referred to as the “Company”, “we”, “us” or “our” or similar terms). All intercompany accounts and transactions have been eliminated. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 . The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant items requiring the use of management estimates and assumptions relate to inventory reserves, bad debt reserves, environmental and asset retirement obligations, workers’ compensation liabilities, reserves for contingencies and litigation and fair value of financial instruments and business acquisitions. Management bases its estimates on the Company’s historical experience and its expectations of the future and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Recent Accounting Pronouncements Adopted In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360)-Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"). Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. ASU 2014-08 became effective for public companies for annual periods beginning on or after December 15, 2014 and interim periods within those years. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under current standards. These changes also require expanded disclosures for all disposals of components of an entity, whether or not the threshold for reporting as a discontinued operation is met, related to profit or loss information and/or asset and liability information of the component. The adoption of this guidance had no impact on the Consolidated Financial Statements. This guidance will need to be considered in the event the Company initiates a disposal of a component. Issued In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Cost Associated with Line-of-Credit Arrangements (Topic 835) ("ASU 2015-15") as the guidance in ASU No. 2015-03, Interest - Imputation of Interest (Topic 835) ("ASU 2015-03") issued in April 2015 did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 allows entities to defer and present debt issuance costs related to line-of-credit arrangements as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company currently presents debt issuance costs related to line-of-credit arrangements as an asset and therefore adoption of this guidance has no impact on its financial position nor results of operations. In April 2015, the FASB issued ASU 2015-03, which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-03 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on its financial position and results of operations. In February 2015, The FASB issued ASU No. 2015-02, Consolidation (Topic 810) ("ASU 2015-02") which updates the considerations on whether an entity should consolidate certain legal entities. The update changes the way that entities evaluate limited partnerships and fees paid to service providers in the consolidation determination. ASU 2015-02 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. We do not expect the adoption of ASU 2015-02 to have a material impact on our Consolidated Financial Statements. In January 2015, The FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Topic 835) ("ASU 2015-01") , which eliminates the concept of extraordinary items. The update simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. ASU 2015-01 will become effective for all entities during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We do not expect the adoption of ASU 2015-01 to have a material impact on our Consolidated Financial Statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40) - Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15), which requires entities to evaluate their ability to continue as a going concern within one year after the date that the financial statements are issued. Disclosure is required if there is substantial doubt about an entity’s ability to continue as a going concern. The guidance in ASU No. 2014-15 is effective for annual and interim periods ending after December 15, 2016 with early application permitted. The Company does not expect that the adoption of this ASU will have a material impact on our Consolidated Financial Statements. In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (“IFRS”). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU 2014-09 was to be effective for public entities for annual and interim periods beginning after December 15, 2016; however, in August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) and delayed the effective date of the new revenue standard by one year. Reporting entities may choose to adopt the standard as of the original effective date. The Company is currently evaluating the impact of adopting this guidance on its financial position and results of operations. There have been no other recently issued accounting updates that had or will have a material impact on the Company’s Interim Financial Statements.

Acquisition of Business

Acquisition of Business	9 Months Ended
	Sep. 30, 2015
Business Combinations [Abstract]
Acquisition of Business	ACQUISITION OF BUSINESS On November 16, 2012, the Company purchased the single membership interest in Mitsui Zinc Powder LLC (“MZP”), a manufacturer of zinc powders for the alkaline battery business, co-located on the Company’s former Monaca facility site, from Oak-Mitsui, Inc. MZP was renamed Horsehead Zinc Powders, LLC. ("HZP"). The Company was MZP's long-term supplier of Special Special High Grade zinc metal used in its production process. The estimated purchase price was $1,101 , which was comprised of $500 in cash at closing, a working capital adjustment and $1,270 in contingent consideration. The contingent consideration consisted of a per ton fee based on tons shipped for a period of time up to a maximum of $1,500 . The acquisition resulted in a gain on bargain purchase. The first two payments related to the contingent consideration were made in 2013. Based upon a decrease in expected production, however, the contingent consideration was reduced by $257 in 2013. During the first quarter of 2014, HZP production was idled due to a lack of raw material supply. Shipments, however, continued through the end of April 2014. As a result, the contingent consideration was reduced by an additional $88 during the first quarter of 2014. This adjustment was recorded in Interest and other income in the Consolidated Statements of Operations. The final payment under the contingent consideration was made in October 2014. On November 7, 2014, the Company announced that Shell Chemical LP ("Shell") had exercised its option under the Amended and Restated Option and Purchase Agreement between Shell and Horsehead Corporation ("Horsehead") to purchase the site of Horsehead’s facility located in Monaca, Pennsylvania, which also included the HZP facility site. The HZP production facility was subsequently demolished under the agreement with Shell. Sale of the site where the Monaca, Pennsylvania facility and HZP facility were located occurred in June 2015. HZP was dissolved on June 2, 2015.

Restructuring and Related Activities [Abstract]
Restructuring Expenses	RESTRUCTURING EXPENSES On October 31, 2013, the Company notified various required parties, as required by the Worker Adjustment and Retraining Notification Act of 1988, 29 U.S.C. § 2101 et seq. , that a majority of its manufacturing operations at the plant located in Monaca, Pennsylvania would be permanently closed and shut down within several months from the notification date. The Company ceased the zinc oxide and high purity zinc metal refinery operations at the Monaca facility on December 23, 2013 and ceased production at the zinc smelter at the end of April 2014. In connection with these actions, the Company permanently terminated the employment of five hundred ten salaried and hourly positions. Costs and the related liabilities due to involuntary termination costs associated with one-time benefit arrangements provided as part of an exit or disposal activities were recognized by the Company when the formal plan for reorganization was approved at the appropriate level of management and communicated to the affected employees. The Company recorded a charge of $7,691 during the fourth quarter of 2013 and an additional charge of $288 during 2014 for severance and other employee-related costs associated with the closing of the Monaca, Pennsylvania facility. Accrual at October 31, 2013 $ 7,517 Adjustments to previously recorded restructuring charges $ 174 Cash payments $ (9 ) Accrual at December 31, 2013 $ 7,682 Adjustments to previously recorded restructuring charges $ 288 Cash payments $ (7,509 ) Accrual at December 31, 2014 $ 461 Cash payments $ (252 ) Accrual at March 31, 2015 $ 209 Cash payments $ (168 ) Remaining accrual at June 30, 2015 $ 41 Cash payments $ (41 ) Remaining accrual at September 30, 2015 $ — Costs associated with exit or disposal activities (e.g., costs to close facilities) are recognized and measured at their fair value in the period in which the liability is incurred. The Company incurred approximately $2.6 million during 2014 related to costs associated with exit and disposal activities and incurred an additional $0.6 million during the first nine months of 2015 and does not expect to incur any additional costs during the remainder of 2015. These costs are included in Cost of sales (excluding depreciation and amortization) in the Consolidated Statement of Operations.

Long -Term Debt	LONG –TERM DEBT Long-term debt consisted of the following at September 30, 2015 and December 31, 2014 : September 30, December 31, Loan Payable, related to New Market Tax Credit program $ 255 $ 255 3.80% Convertible Senior Notes due July 2017, net of debt discount 92,382 89,448 10.50% Senior Secured Notes due June 2017, net of debt premium 205,101 205,169 9.00% Senior Unsecured Notes due July 2017 40,000 40,000 ABL Facility, interest payable at variable rates — 14,830 Macquarie Credit Facility, interest payable at variable rates 59,451 — Zochem Credit Facility, interest payable at variable rates 8,000 19,400 INMETCO Credit Facility, interest payable at variable rates — 20,000 Credit Agreement, interest payable at variable rates 18,226 19,958 423,415 409,060 Less portion currently payable 11,102 3,044 $ 412,313 $ 406,016 Convertible Senior Notes On July 27, 2011, the Company issued $100,000 of 3.80% Convertible Senior Notes due 2017 (the “Convertible Notes”) in a private placement. The Company received proceeds of $100,000 and recognized $3,481 in issuance costs in connection with the offering. The Company used the proceeds from the offering for the initial stages of construction for the new zinc facility and for general corporate purposes, including working capital needs, investment in business initiatives, capital expenditures and acquisitions. The Convertible Notes pay interest semi-annually in arrears on July 1 and January 1 of each year at a rate of 3.80% per annum and mature on July 1, 2017. The Convertible Notes are convertible into shares of the Company’s common stock, cash, or a combination of the Company’s common stock and cash, at the Company’s election, at an initial conversion rate of 0.0666667 shares of the Company’s common stock per $1 principal amount of the Convertible Notes (approximately 6,666.67 underlying shares), which is equivalent to an initial conversion price of approximately $15.00 per share of common stock, subject to adjustment in certain circumstances, as defined in the indenture governing the Convertible Notes. The Company has stated that it intends to settle the par value in cash and the conversion spread in either cash, shares or a combination of both. The Convertible Notes are senior unsecured obligations of the Company and rank senior in right of payment to its future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to its existing and future unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of its secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other liabilities (including trade payables) of its subsidiaries. Holders of the Convertible Notes may convert their Convertible Notes at the applicable conversion rate at any time on or after April 1, 2017 until the close of business on the second business day immediately preceding the maturity date. The Convertible Notes may be converted prior to April 1, 2017 only under certain circumstances. If the Company undergoes a fundamental change, as defined in the indenture governing the Convertible Notes, holders may require the Company to repurchase for cash all or a portion of their notes at a price equal to 100% of the principal amount of the Convertible Notes to be repurchased plus any accrued and unpaid interest up to, but excluding the fundamental change repurchase date. The Company does not have the right to redeem the Convertible Notes prior to the stated maturity date of July 1, 2017 and no sinking fund is provided for the Convertible Notes. In accordance with the guidance under Accounting Standards Codification ("ASC") 815-15 Embedded Derivatives and ASC 470-20 Debt with Conversion and other Options, the Company separately accounted for the liability and equity components of the Convertible Notes to reflect the Company’s nonconvertible borrowing rate when interest cost is recognized in subsequent periods. The fair value of the liability component of the Convertible Notes was calculated to be $78,174 and was determined by measuring the fair value of a similar liability that does not have an associated equity component. The nonconvertible rate was determined by the Company to be 8.5% . The carrying amount of the embedded conversion option (the debt discount) of $21,826 was determined by deducting the fair value of the liability component from the initial proceeds of the Convertible Notes and was recorded, net of deferred taxes of $8,805 , as additional paid-in capital. The Company is accreting the long-term debt balance to par value over the term of the bonds using the interest method as required by ASC 835-30 Imputation of Interest. The indenture governing the Convertible Notes contains customary reporting and other covenants. The Company was in compliance with all covenants at September 30, 2015. Costs of $3,481 associated with the issuance were allocated to the liability and equity components in proportion to the allocation of the fair value of the Convertible Notes. As such, $2,721 was accounted for as debt issuance costs attributable to the liability component of the Convertible Notes and were capitalized as a component of other assets. These costs are being amortized to interest expense over the term of the Convertible Notes and are included as a component of interest expense. The Company recognized interest expense of $115 and $345 related to the amortization of debt issuance costs during both the three and nine months ended September 30, 2015 and 2014 , respectively. The remaining issuance costs of $760 were accounted for as equity issuance costs and were recorded in additional-paid in capital. During the three and nine months ended September 30, 2015 , the Company recognized $1,948 and $5,784 , respectively, in interest expense related to the Convertible Notes. During the three and nine months ended September 30, 2014 , the Company recognized $1,868 and $5,546 , respectively, in interest expense related to the Convertible Notes. Interest expense includes the contractual interest coupon of 3.80% and amortization of the discount on the liability component. This interest expense reflects an effective interest rate of 8.50% . The carrying amount of the Convertible Notes was $92,382 with an unamortized discount of $7,618 at September 30, 2015 . The carrying amount of the Convertible Notes was $89,448 with an unamortized discount of $10,552 at December 31, 2014 . The carrying amount of the equity component was $4,206 and $6,052 at September 30, 2015 and December 31, 2014 , respectively. The accumulated accretion related to the equity component was $8,815 and $6,969 at September 30, 2015 and December 31, 2014 , respectively. The fair value of the Convertible Notes was estimated to be approximately $67,000 and $122,000 at September 30, 2015 and December 31, 2014 , respectively, per pricing obtained from a pricing data service. The data service triangulates pricing based on market indications and their quotes do not represent actual trades only implied pricing based on the bid-ask in the market. ABL Facility On September 28, 2011, the Company’s subsidiary Horsehead entered into an ABL Facility (the "ABL Facility"), as borrower, with PNC Bank, as agent and lender, to support liquidity needs for the Company’s new zinc facility and to allow for the availability of previously restricted cash. Horsehead Holding Corp. also entered into the ABL Facility, as guarantor of Horsehead’s obligations. The ABL Facility provided for a five -year senior secured revolving credit facility in an aggregate principal amount of up to $60,000 . The aggregate amount of loans permitted to be made under the revolving credit facility could not exceed a borrowing base consisting of the lesser of: (a) $60,000 , minus the aggregate undrawn amount of outstanding letters of credit, or (b) the sum of certain portions of eligible accounts receivable and eligible inventory of Horsehead, minus the aggregate undrawn amount of outstanding letters of credit and certain availability reserves. Up to an aggregate of $30,000 was available to Horsehead for the issuance of letters of credit, which reduced availability under the ABL Facility. The ABL Facility was terminated on July 6, 2015 when a new $80,000 secured revolving credit facility became effective among Horsehead, HMP, The International Metals Reclamation Company, LLC (“INMETCO”) and Macquarie Bank Limited, as administrative agent and sole arranger (the "Macquarie Credit Facility"). The Macquarie Credit Facility replaces both the $20,000 INMETCO Facility (as defined below) and the $60,000 ABL Facility. The Company incurred total issuance costs of $600 in connection with the ABL Facility. These costs were capitalized in the Company’s Consolidated Balance Sheet as a component of other assets. The issuance costs were being amortized to interest expense over the term of the ABL Facility. The remaining unamortized issuance costs of $201 related to the ABL Facility were written off to interest expense during the three months ended September 30, 2015. Interest expense of $201 and $37 related to the amortization of deferred finance costs was recorded during the three months ended September 30, 2015 and 2014 , respectively and interest expense of $277 and $82 was recorded during the nine months ended September 30, 2015 and 2014 , respectively.

The Company received proceeds of $171,829 and recognized approximately $7,732 in issuance costs in connection with the offering. The total net proceeds from the offering were $164,097 . The Company used the proceeds from the Secured Notes to pay for the completion of the construction of the Company’s new zinc facility and the remainder for general corporate purposes, including working capital needs, investment in other business initiatives and other capital expenditures. The Company recorded an initial debt carrying value of $171,829 (net of the debt discount of $3,171 ) and is accreting the long-term debt balance to par value over the term of the Secured Notes using the interest method as required by ASC 835-30 Imputation of Interest. Interest expense includes the contractual interest coupon of 10.50% and amortization of the debt discount to reflect an effective interest rate of 11.00% . On June 3, 2013, the Company completed the sale to certain purchasers of an additional $20,000 in aggregate principal amount of the Company's Secured Notes (the “2013 Additional Notes”) at an issue price of 106.5% of the principal amount of the 2013 Additional Notes plus accrued interest from June 1, 2013, in a private placement. The Company received net proceeds of $20,955 after deducting approximately $345 in issuance costs in connection with the offering. The Company recorded an initial debt carrying value of $21,300 (including the debt premium of $1,300 ) and is amortizing the long-term debt balance to par value over the remaining term of the Secured Notes using the interest method as required by ASC 835-30 Imputation of Interest.

The Senior Secured Notes mature on June 1, 2017. The Company recorded interest expense of $5,360 and $5,307 for the three months ended September 30, 2015 and 2014 , respectively, and $16,076 and $15,697 during the nine months ended September 30, 2015 and 2014 , respectively.

The Senior Secured Notes and the guarantees rank equal in right of payment with any of the Company’s and the Guarantors’ senior indebtedness, including indebtedness under the Macquarie Credit Facility and, in the case of the Company, the Company’s Convertible Notes. The Senior Secured Notes and the guarantees rank senior in right of payment to any of the Company’s and the Guarantors’ future indebtedness that is expressly subordinated to the Senior Secured Notes or guarantees. The Senior Secured Notes and the guarantees are effectively senior to any of the Company’s or the Guarantors’ unsecured indebtedness, including the Convertible Notes, to the extent of the value of the collateral securing the Senior Secured Notes, and the Senior Secured Notes are effectively senior to indebtedness of the Company that is not guaranteed by the Guarantors, including the Company’s Convertible Notes, to the extent of the value of the guarantees.

Up to an aggregate of $5,000 is available to Zochem for the issuance of letters of credit, which reduces availability under the 2014 Zochem Facility. Zochem’s obligations under the 2014 Zochem Facility are secured by a first priority lien (subject to certain permitted liens) on substantially all of the tangible and intangible assets of Zochem. At September 30, 2015 , the Company had $8,000 in outstanding borrowings which are all classified as current due to the upcoming expiration of the facility in September 2016. There was $11,592 in undrawn availability at September 30, 2015 . The carrying amount of the debt approximated fair value at September 30, 2015 . Borrowings by Zochem under the 2014 Zochem Facility bear interest at a rate per annum which, at the option of Zochem, can be either: (a) a domestic rate equal to the “alternate base rate,” as determined under the 2014 Zochem Facility, plus an applicable margin of 1.00% based on average undrawn availability, or (b) a CDOR, LIBOR or eurodollar rate as applicable, plus a margin of 2.50% based on average undrawn availability. Zochem pays a letter of credit fee to the lenders under the Zochem Facility of 2.50% , based on average undrawn availability, and a fronting fee to the issuing bank equal to 0.25% per annum on the average daily face amount of each outstanding letter of credit, as well as certain other related charges and expenses. Zochem pays an unused line fee to the lenders of 0.75% per annum, based on average undrawn availability, times the amount by which the maximum revolving advance amount exceeds the average daily unpaid balance of revolver loans and undrawn amount of any outstanding letters of credit during any calendar quarter. The 2014 Zochem Facility contains customary events of default. During an event of default, if the agent or lenders holding greater than 66 2/3% of the advances under the facility so elect, the interest rate applied to any outstanding obligations would be equal to the otherwise applicable rate (including the highest applicable margin) plus 2.0% and any letter of credit fees would be increased by 2.0% . Upon (a) the occurrence of an event of default related to the bankruptcy of Zochem or the Company or (b) at the option of lenders holding greater than 66 2/3% of the advances under the facility, the occurrence of any other event of default, all obligations under the 2014 Zochem Facility will become immediately due and payable. The 2014 Zochem Facility also contains a minimum fixed charge coverage ratio of 1.15 :1.00 which Zochem must comply with at the time of any advance request. The 2014 Zochem Facility also contains customary restrictive negative covenants as well as customary reporting and other affirmative covenants.

The Unsecured Notes and the guarantees (i) rank equal in right of payment with the Company’s and the Guarantors’ senior indebtedness (other than as described below) (including indebtedness under the Company's Senior Secured Notes due 2017, the Convertible Notes due 2017, and the Macquarie Credit Facility, dated as of July 6, 2015); (ii) rank senior in right of payment with the Company’s and the Guarantors’ future indebtedness that is expressly subordinated to the Unsecured Notes and (iii) is effectively junior to the Company’s and the Guarantors’ obligations under the Senior Secured Notes and the Macquarie Credit Facility, to the extent of the value of the collateral securing such indebtedness. The Company may redeem some or all of the Unsecured Notes, on or after June 1, 2016 at a redemption price equal to 104.50% , plus accrued and unpaid interest, if any, to the date of redemption. In addition, the Company may, at its option, redeem some or all of the Unsecured Notes prior to June 1, 2016, by paying a make-whole premium, plus accrued and unpaid interest, if any, to the date of redemption. The indenture, governing the Unsecured Notes, contains covenants that limit the Company’s ability and the ability of its restricted subsidiaries to, among other things: (i) incur additional indebtedness and guarantee indebtedness; (ii) declare or pay dividends, redeem capital stock or make other distributions to stockholders; (iii) make investments and acquire assets; (iv) sell or transfer certain assets; (v) enter into transactions with affiliates; (vi) create liens or use assets as security in other transactions; (vii) enter into sale and leaseback transactions; (viii) merge or consolidate, or sell, transfer, lease or dispose of substantially all of its assets; and (ix) make certain payments on indebtedness. The Unsecured Notes Indenture also provides for customary events of default. The Company was in compliance with all debt covenants as of September 30, 2015 . Costs of $1,314 associated with the issuance of the Unsecured Notes were capitalized as a component of other assets. These costs are being amortized to interest expense over the term of the Unsecured Notes. The Company recognized interest expense of $116 and $348 related to the amortization of debt issuance costs during the three and nine months ended September 30, 2015 , respectively. The Company recognized interest expense of $71 during the three and nine months ended September 30, 2014 . The fair value of the Unsecured Notes was estimated to be approximately $38,000 at September 30, 2015 and $40,000 at December 31, 2014 per pricing obtained from a pricing data service. The data service triangulates pricing based on market indications and their quotes do not represent actual trades only implied pricing based on the bid-ask in the market. Macquarie Revolving Credit Facility On June 30, 2015, the Company's wholly owned direct and indirect subsidiaries, INMETCO, Horsehead Corporation and HMP, entered into the Macquarie Credit Facility with Macquarie Bank Limited, which became effective on July 6, 2015. The Macquarie Credit Facility matures on May 15, 2017. The new $80,000 facility replaces both the ABL Facility and the INMETCO Facility. The Macquarie Credit Facility is the same maximum principal amount, and is secured by the same collateral of such subsidiaries. However, the new credit facility accommodates a broader borrowing base than the two previous credit facilities. The Company had $59,451 in outstanding borrowings and $20,549 in undrawn availability at September 30, 2015 . The carrying amount of the debt approximated fair value at September 30, 2015 . The aggregate amount of loans permitted to be made under the revolving credit facility may not exceed a borrowing base of $80,000 . The available borrowing base consists of the sum of a portion of eligible cash on hand, accounts receivable, inventory and other eligible amounts as determined by the credit agreement governing the Macquarie Credit Facility. Borrowings under the Macquarie Credit Facility bear interest at a rate per annum, which is the sum of the designated LIBOR rate plus an applicable margin of 4.10% . The Company pays an unused line fee to the lenders of 1.5% per annum, based on average undrawn availability, times the amount by which the maximum revolving advance amount exceeds the average daily unpaid balance of revolver loans. The Macquarie Credit Facility contains customary restrictive negative covenants as well as customary reporting and other affirmative covenants. Additionally, the Company must be in complianc

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company’s effective tax rates were 36.5% and 50.8% for the three months ended September 30, 2015 and 2014 , respectively, and 37.1% and 42.6% for the nine months ended September 30, 2015 and 2014 , respectively. Income tax expense (benefit) differs from the amount computed by applying the U.S. statutory federal income tax rate of 35% to income before income taxes, due to state income taxes, a lower income tax rate on Canadian income and the impact of permanent differences. The effective tax rate for the nine months ended September 30, 2015 decreased when compared to the nine months ended September 30, 2014 due to higher than previously projected pretax losses during 2015 which increased the valuation allowance related to state net operating losses and also diluted the impact of lower foreign subsidiary statutory tax rates impact on the overall effective rate. During the nine months ended September 30, 2015, pretax losses created future net operating loss deductions for both federal and state purposes resulting in a long term deferred tax asset of $21,060 at September 30, 2015. The long term deferred tax asset is recorded in the Company's Consolidated Balance Sheet. The Company and its subsidiaries file income tax returns in the U.S., Canada and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. The tax years that remain subject to examination are 2009 through 2014. U.S. income taxes and foreign withholding taxes are not provided on undistributed earnings of foreign subsidiaries because it is expected such earnings will be permanently reinvested in the operations of such subsidiaries. It is not practical to determine the amount of income tax liability that would result had such earnings been repatriated.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION In 2006, the Company adopted the Horsehead Holding Corp. 2006 Long-Term Equity Incentive Plan (the “2006 Plan”), which was amended and restated on June 11, 2007, and provided for grants of stock options, stock appreciation rights, restricted stock, restricted stock units, deferred stock units and other equity-based awards. Directors, officers and other employees of the Company, as well as others performing services for the Company, were eligible for grants under the 2006 Plan. The 2006 Plan is administered by the compensation committee of the Company’s Board of Directors (the “Compensation Committee”). On January 16, 2007, the Board authorized the issuance of options to purchase 1,085 shares of the Company’s common stock to certain officers and employees of the Company under the terms of the 2006 Plan. The options have a term of ten years and vest ratably over a five -year period from date of grant. During the nine months ended September 30, 2015 , 3 stock options were exercised and the Company received proceeds of $33 from the exercise of these options. At September 30, 2015 , there were 580 options still outstanding; all were fully vested and exercisable, each with an exercise price of $13.00 per share and 1.29 years of remaining contractual life. The options outstanding under the 2006 Plan had no intrinsic value at September 30, 2015 . All compensation expense had been recognized as of March 31, 2012. The Company had a total of 422 restricted stock units at a weighted average grant date fair value of $10.99 per unit outstanding under the 2006 Plan at December 31, 2014 . During the nine months ended September 30, 2015 , 203 restricted stock units vested having an intrinsic value of $3,039 . At September 30, 2015 , there were 219 restricted stock units outstanding and the remaining contractual life ranged from 0.25 years to 2.00 years. The related compensation expense for the three months ended September 30, 2015 and 2014 was $250 and $337 , respectively and the related compensation expense was $788 and $1,065 during the nine months ended September 30, 2015 and 2014 , respectively. These expenses are included in Selling, general and administrative expenses in the Consolidated Statement of Operations. Unrecognized compensation expense as of September 30, 2015 was $705 . On May 17, 2012, the Company adopted the Horsehead Holding Corp. 2012 Incentive Compensation Plan (“2012 Plan”), after it was approved by the Company’s stockholders at the 2012 Annual Meeting of Stockholders. The 2012 Plan replaced the 2006 Plan, and no further awards, stock options or other grants will be issued under the 2006 Plan. The 2012 Plan provides for grants of stock options, stock appreciation rights, restricted stock, restricted stock units and other cash or equity-based awards. Directors, officers and other employees of the Company, as well as others performing consulting or advisory services for the Company, are eligible for grants under the 2012 Plan. The 2012 Plan is administered by the Compensation Committee. A total of 2,700 shares of the Company’s common stock were initially authorized for issuance under the 2012 Plan. The number of shares available for issuance under the 2012 Plan is subject to adjustment in the event of a reorganization, stock split, merger or similar change in the corporate structure or the number of outstanding shares of common stock. In the event of any of these occurrences, the Compensation Committee may make any adjustments considered appropriate to, among other things, the number and kind of shares, options or other property available for issuance under the 2012 Plan or covered by grants previously made under the 2012 Plan. The shares available for issuance under the 2012 Plan may be, in whole or in part, authorized and unissued or held as treasury shares. If awards under the 2012 Plan are for any reason canceled, or expire or terminate unexercised, the shares covered by such awards may again be available for the grant of awards under the 2012 Plan. The Company had a total of 579 restricted stock units at a weighted average grant date fair value of $18.66 per unit outstanding under the 2012 Plan at December 31, 2014 . During the nine months ended September 30, 2015 , the Company granted 126 service based restricted stock units with an average grant date fair value of $15.74 per unit. The restricted stock units vest over a one or five -year service period. During the nine months ended September 30, 2015 , 23 restricted stock units vested having an intrinsic value of $359 . During the nine months ended September 30, 2015 , the Company granted 105 restricted stock units to management based on the future achievement of a predefined level of total shareholder return compared to a group of global metals companies. The fair value at the date of grant for these restricted stock units was $21.92 per unit, as estimated by a third party on the date of grant, using a valuation model based on commonly accepted economic theory which is used for all valuations of awards with market conditions. This economic theory is also used as the basis for the Black-Scholes and Monte Carlo valuations. The significant assumptions were a risk free rate of 1.07% , expected volatility of the Company and each comparator company, no expected dividends and a forfeiture rate of zero . A vesting percentage was then estimated based on the Company’s rank within the comparator group. Upon vesting and the achievement of the required shareholder return, these restricted stock units will be issued for par value. The related compensation expense for all 2012 Plan restricted stock units for the three months ended September 30, 2015 and 2014 was $1,108 and $836 , respectively. The related compensation expense was $3,317 and $2,517 during the nine months ended September 30, 2015 and 2014 , respectively. These expenses are included in Selling, general and administrative expenses in the Consolidated Statement of Operations. The remaining contractual life ranged from 0.25 years to 4.75 years. Unrecognized compensation expense as of September 30, 2015 was $6,895 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Accounting for Derivative Instruments and Hedging Activities	ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company’s business consists principally of the sale of zinc and nickel-based products. As a result, its results of operations are subject to risk of fluctuations in the market prices of these metals. While the Company’s finished products are generally priced based on a spread to the price of zinc or nickel, as applicable, on the LME, its revenues are impacted significantly by changes in the market prices of these metals. The Company pursues various hedging strategies as described below to reduce its exposure to movements in the prices of zinc and nickel. The Company’s marketing strategy includes a metal hedging program that allows customers to secure a firm price for future deliveries under a sales contract. Hedges are entered into based on firm sales contracts to deliver specified quantities of product on a monthly basis for terms generally not exceeding one year. A portion of the Company’s raw material purchases related to such firm price contracts are at varying zinc prices that are based on the LME. In order to protect its cash flow related to firm price sales contracts, the Company enters into fixed-to-variable swap contracts to convert the LME-based fixed sales price back to variable. Thus, if raw material costs increase as a result of LME zinc price increases, the related sales value and related cash flows will also increase. As of September 30, 2015 , the fixed portions of these contracts ranged from a monthly average of $0.75 to $1.01 per pound for zinc. The Company has hedged approximately 16.7 tons of zinc with fixed-to-variable future swap contracts at September 30, 2015 , all of which settle at various dates up to and including December 31, 2016 . The Company also enters into variable-to-fixed swap contracts as a financial hedge of a portion of its exposure to the movements in the LME prices of nickel. As of September 30, 2015 , the Company had a small amount of nickel swap contracts in place. The fixed portions of these contracts were at a monthly average of $4.42 per pound for nickel and settle at various dates up to and including December 31, 2016 . The Company paid cash of $2,306 and $2,815 from the settlement of zinc and nickel swap contracts for the three and nine months ended September 30, 2015 , respectively, and paid cash of $109 and $676 for the three and nine months ended September 30, 2014 , respectively. In 2014, the Company entered into fixed rate swaps, which were put in place to reduce volatility during the completion of construction and ramp-up of production at the new zinc facility. During 2014, the Company added fixed price swaps for the second quarter of 2014, at an average price of approximately $0.94 per pound for a total quantity covered of 26.5 tons for the quarter, zinc fixed price swaps for the months of August and September 2014, at an average price of slightly over $1.07 per pound for a total quantity covered of 6.0 tons per month and zinc fixed price swaps for the months of November and December 2014, at an average price of slightly over $1.05 per pound for a total quantity covered of 6.6 tons per month. During the first quarter of 2015, the Company added zinc fixed price swaps for the month of February 2015 at an average price of approximately $0.97 per pound for a total quantity covered of approximately 3.3 tons and zinc fixed price swaps for the months of April and May 2015 at an average price of approximately $0.94 per pound for a total quantity covered of approximately 6.6 tons per month. During the second quarter of 2015, the Company added zinc fixed price swaps for the month of June 2015 at an average price of approximately $1.01 per pound for a total quantity covered of approximately 9.9 tons, fixed price swaps for the third quarter of 2015 at an average price of $1.07 per pound for a total quantity covered of approximately 18.2 tons and fixed price swaps for the fourth quarter of 2015 at an average price of $1.07 for a total quantity covered of approximately 16.9 tons. The Company received cash of $8,255 and $7,522 from the settlement of zinc fixed price swaps during the three and nine months ended September 30, 2015 , respectively, and received cash of $535 but paid cash of $512 during the three and nine months ended September 30, 2014 , respectively. In October 2015, the Company added zinc fixed price swaps for the first quarter of 2016 at an average price of approximately $0.83 per pound for a total quantity covered of approximately 5.0 tons. The gains and losses resulting from the Company’s hedging activities are recorded in the Consolidated Statements of Operations as indicated in the table below.

The swap valuations are based on the official LME closing valuations at the end of the trading day on September 30, 2015 and December 31, 2014 , using the mid-point of the closing bid and ask prices on all open swap positions regardless of the holder. The closing prices are supervised by the London Clearing House and are regulated by the Financial Services Authority, the financial regulatory body in the United Kingdom. The Company is exposed to credit loss in cases where counterparties with which they have entered into derivative transactions are unable to pay when they owe the Company funds as a result of agreements with them. To minimize the risk of such losses, the Company utilizes eight different brokers for their hedging program. The Company does not require collateral and does not enter into master netting arrangements.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings (loss) per common share (“EPS”) is computed by dividing net income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per share are computed similarly to basic earnings per share except that the denominator is increased to include the number of shares that would have been outstanding if the potentially dilutive common shares had been issued. The Company uses the treasury stock method when calculating the dilutive effect in basic EPS. Diluted EPS for periods with a net loss is calculated by dividing the net loss by the weighted average number of basic shares outstanding. The information used to compute basic and diluted loss per share is as follows: Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 Basic loss per share: Net loss $ (27,376 ) $ (7,010 ) $ (49,489 ) $ (11,401 ) Weighted average shares outstanding – basic 56,664 50,715 56,062 50,670 Basic loss per share $ (0.48 ) $ (0.14 ) $ (0.88 ) $ (0.23 ) Diluted loss per share: Net loss $ (27,376 ) $ (7,010 ) $ (49,489 ) $ (11,401 ) Weighted average shares outstanding – diluted 56,664 50,715 56,062 50,670 Diluted loss per share $ (0.48 ) $ (0.14 ) $ (0.88 ) $ (0.23 ) Reconciliation of average shares outstanding – basic to average shares outstanding – diluted: Weighted average shares outstanding – basic 56,664 50,715 56,062 50,670 Effect of dilutive securities: Options — — — — Convertible Notes — — — — Restricted stock units — — — — Weighted average shares outstanding – diluted 56,664 50,715 56,062 50,670 Exercise Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 Anti-dilutive shares excluded from earnings per share calculation Options $ 13.00 580 584 581 584 Convertible Notes $ 15.00 — 1,406 — 896 Restricted Stock Units 1,011 1,001 1,017 1,033 Total 1,591 2,991 1,598 2,513 On July 27, 2011, the Company issued $100,000 of Convertible Notes. The Convertible Notes are convertible at a conversion price of approximately $15.00 per share into cash, shares or a combination of both at the Company’s election. According to guidance under ASC 260 Earnings Per Share, if an entity issues a contract that may be settled in common stock or cash at the election of the entity or holder, then it is presumed that the contract will be settled in shares unless past experience or a stated policy provides a reasonable basis to believe that the contract will be paid partially or wholly in cash and the “if converted” method shall not be used. The Company has stated that it intends to settle the par value in cash and the conversion spread in either cash, shares or a combination of both. The Company utilizes the modified treasury stock method and assumes dilution if the average stock price for the quarter exceeds the conversion price. The share dilution is calculated by dividing the conversion spread value by the average share price for the quarter. During the three and nine months ended September 30, 2015 , the average share price for the quarter was lower than the exercise price for the Convertible Notes and therefore no conversion spread was realized and no dilution assumed.

Subsequent Events [Abstract]
Subsequent Event	SUBSEQUENT EVENT On October 23, 2015, the Company entered into an At-The-Market Equity Offering sales agreement pursuant to which the Company may offer and sell, from time to time, shares of its common stock having an aggregate offering price of up to $50,000 , through the sales agent. Subject to the terms and conditions of the sales agreement, the sales agent will use its commercially reasonable efforts to sell shares of the Company’s common stock in such number, at such times and at such prices as the Company shall determine. However, the Company is not required to sell any shares of its common stock at any time. Sales of the shares of the Company’s common stock, if made, may be made by any method deemed to be an “at-the-market offering” as defined in Rule 415 under the Securities Act of 1933, as amended, including, sales made directly on or through the NASDAQ Global Select Market, the existing trading market for the Company’s common stock or sales made to or through a market maker other than on an exchange, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices. The offering is being made under the Company’s registration statement on Form S-3 which became effective October 3, 2013. The sales agreement will terminate on the earlier of (i) the sale of all of the common stock subject to the sales agreement or (ii) termination of the sales agreement in accordance with its terms. The Company intends to use the net proceeds from the sale of the shares of its common stock, if any, for general corporate purposes, which may include liquidity for operational contingencies, working capital and capital expenditures. In October 2015, the Company received a tax certification notice from the state of North Carolina that it had qualified for and been approved for a tax credit on the eligible assets related to its recycling equipment at its facility located in Mooresboro, North Carolina. The Company is eligible to a receive a tax credit not to exceed 50% of its verified equipment which exceeded $500 million in total cost. During the fourth quarter of 2015, the Company will record the related tax benefit less any required valuation allowance. On November 8, 2015, a fire damaged a battery storage building at our INMETCO facility located in Ellwood City, Pennsylvania. The fire did not affect the facility’s primary operations, however, the cause of the fire and the full extent of the damage are not known at the time of this filing. The Company maintains property and business interruption insurance coverage.

Basis of Presentation Basis of Presentation (Policies)	9 Months Ended

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360)-Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"). Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. ASU 2014-08 became effective for public companies for annual periods beginning on or after December 15, 2014 and interim periods within those years. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under current standards. These changes also require expanded disclosures for all disposals of components of an entity, whether or not the threshold for reporting as a discontinued operation is met, related to profit or loss information and/or asset and liability information of the component. The adoption of this guidance had no impact on the Consolidated Financial Statements. This guidance will need to be considered in the event the Company initiates a disposal of a component. Issued In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Cost Associated with Line-of-Credit Arrangements (Topic 835) ("ASU 2015-15") as the guidance in ASU No. 2015-03, Interest - Imputation of Interest (Topic 835) ("ASU 2015-03") issued in April 2015 did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 allows entities to defer and present debt issuance costs related to line-of-credit arrangements as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company currently presents debt issuance costs related to line-of-credit arrangements as an asset and therefore adoption of this guidance has no impact on its financial position nor results of operations. In April 2015, the FASB issued ASU 2015-03, which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-03 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on its financial position and results of operations. In February 2015, The FASB issued ASU No. 2015-02, Consolidation (Topic 810) ("ASU 2015-02") which updates the considerations on whether an entity should consolidate certain legal entities. The update changes the way that entities evaluate limited partnerships and fees paid to service providers in the consolidation determination. ASU 2015-02 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. We do not expect the adoption of ASU 2015-02 to have a material impact on our Consolidated Financial Statements. In January 2015, The FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Topic 835) ("ASU 2015-01") , which eliminates the concept of extraordinary items. The update simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. ASU 2015-01 will become effective for all entities during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We do not expect the adoption of ASU 2015-01 to have a material impact on our Consolidated Financial Statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40) - Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15), which requires entities to evaluate their ability to continue as a going concern within one year after the date that the financial statements are issued. Disclosure is required if there is substantial doubt about an entity’s ability to continue as a going concern. The guidance in ASU No. 2014-15 is effective for annual and interim periods ending after December 15, 2016 with early application permitted. The Company does not expect that the adoption of this ASU will have a material impact on our Consolidated Financial Statements. In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (“IFRS”). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU 2014-09 was to be effective for public entities for annual and interim periods beginning after December 15, 2016; however, in August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) and delayed the effective date of the new revenue standard by one year. Reporting entities may choose to adopt the standard as of the original effective date. The Company is currently evaluating the impact of adopting this guidance on its financial position and results of operations. There have been no other recently issued accounting updates that had or will have a material impact on the Company’s Interim Financial Statements.
