SOLICITATION OF PROXIES

The information contained in this proxy statement is furnished in connection
with the solicitation of proxies to be used at the Annual and Special Meeting of
Shareholders (the "Meeting") of Zemex Corporation (the "Corporation" or
"Zemex"), a company incorporated under the Canada Business Corporations Act, to

being mailed to the Corporation's shareholders commencing on or about May 18,
2000. The Corporation's Annual Report on Form 10-K for the year ended December
31, 1999, which includes its financial statements, was mailed on or about April
14, 2000 to each shareholder of record as of the close of business on March 30,
2000. Such annual report, however, is not to be deemed to be part of this proxy
solicitation material.

THE CORPORATION WILL PROVIDE, WITHOUT CHARGE, A COPY OF ITS ANNUAL REPORT ON
FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 1999 TO ANY SHAREHOLDER WHOSE PROXY
IS SOLICITED HEREBY, UPON WRITTEN REQUEST DIRECTED TO THE CORPORATE SECRETARY
AND ASSISTANT TREASURER, ZEMEX CORPORATION, CANADA TRUST TOWER, BCE PLACE, 161
BAY STREET, SUITE 3750, TORONTO, ONTARIO, M5J 2S1.

The expense of solicitation of proxies will be borne by the Corporation.
Following the mailing of the proxy material, solicitation of proxies may be made
by mail, telephone, facsimile, telegram or personal interview by directors,
officers or regular employees of the Corporation or its subsidiaries, who will
receive no additional compensation for their services. The Corporation has also
retained Georgeson Shareholder Communications Inc. to solicit proxies personally
or by mail, telephone, facsimile, or telegraph from brokerage houses,
custodians, fiduciaries and nominees for a fee of $4,500 plus expenses. In
addition, the Corporation will reimburse brokers and other nominees for their
expenses in forwarding soliciting material to beneficial owners.

VOTING SECURITIES AND PRINCIPAL HOLDERS THEREOF

The Corporation's board of directors (the "Board") has fixed the close of
business on May 17, 2000 as the record date for the determination of
shareholders of the Corporation entitled to vote at the Meeting. As of April 30,
2000, the Corporation had approximately 8,899,224 common shares (the "Common
Shares") issued and outstanding.

Each Common Share is entitled to one vote. Two shareholders present in person or
by proxy are required in order to constitute a quorum for the transaction of
business. Abstentions are treated as present and entitled to vote, and will have
the effect of a vote against any matter requiring the affirmative vote of a
majority of the Common Shares present and entitled to vote at the Meeting.

As indicated on page 7 under the heading "Principal Shareholders and Security
Ownership of Management", The Dundee Bank, beneficially owns 33.8% of the issued
and outstanding Common Shares of the Corporation.

A board of eight directors is to be elected at the Meeting. All directors so
elected will hold office until the next annual meeting of shareholders of the

nominee designated by the present Board to fill the vacancy.

Unless otherwise instructed, the management representatives named in the
enclosed form of proxy will vote the proxies received by them for the
Corporation's eight nominees named below, all of whom are presently directors of
the Corporation, unless the shareholder who has given such proxy has directed
that the shares be withheld from voting in the election of directors.

Opposite the name of each nominee for election as a director is (i) his age;
(ii) his position with the Corporation, his principal occupation and his
business experience during the past five years; and (iii) the year in which he
first became a director of the Corporation. All information is as of April 15,

                                    AUDITORS


RATIFICATION OF AUDITORS

Deloitte & Touche LLP, independent certified public accountants, were first
appointed auditors of the Corporation in 1993. The management representatives in
the enclosed form of proxy intend to vote the shares represented by such proxy
in favour of a resolution ratifying the appointment of Deloitte & Touche LLP as
independent auditors of the accounts of the Corporation and its subsidiaries for
the fiscal year ending December 31, 2000 and authorizing the Board to fix the
remuneration of the auditors, unless the shareholder who has given such proxy
has directed that the shares represented thereby be withheld from voting in the
ratification of the appointment of auditors. Representatives of Deloitte &
Touche LLP will be present at the Meeting and will be available to respond to
questions and may make a statement if they so desire.

VOTE REQUIRED FOR RATIFICATION OF AUDITORS

Ratification of the appointment of the auditors requires the affirmative vote of
a majority of the votes cast by holders of shares represented in person or by
proxy.

THE BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE
RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS INDEPENDENT AUDITORS
FOR THE FISCAL YEAR ENDING DECEMBER 31, 2000.

                                  PROPOSAL III
           INCREASE IN NUMBER OF COMMON SHARES RESERVED FOR ISSUANCE
                 UNDER THE CORPORATION'S 1999 STOCK OPTION PLAN

On October 20, 1999, the Board approved a resolution increasing the number of
Common Shares reserved for issuance under the Corporation's 1999 Stock Option
Plan, a plan which was approved by the Corporation's shareholders on May 10,
1999 (the "1999 Stock Option Plan"), to 372,543, or 4.2% of the Corporation's
then issued and outstanding capital. This represents an increase of 100,000
Common Shares over the number of Common Shares currently reserved for issuance
under the 1999 Stock Option Plan, of which 270,650 options are outstanding. The
Board approved the increase based on, among other things, a determination that
the remaining number of Common Shares reserved for issuance under the 1999 Stock
Option Plan was insufficient to incentivize and reward officers, directors and
employees who join the Corporation or deserve to be rewarded for their service
and dedication to the Corporation.

Any increase in the number of Common Shares reserved for issuance under a stock
option plan is subject to approval by The Toronto Stock Exchange (the "TSE").
The Corporation received conditional approval from the TSE on December 21, 1999
with respect to the foregoing increase, subject to approval of the Corporation's
shareholders.

Under the TSE's rules, all interested parties (being parties currently holding
options under the Plan) must refrain from voting their Common Shares, whether
held directly or indirectly, on the motion to approve the increase in the number
of Common Shares reserved for issuance under the 1999 Stock Option Plan. As of
April 15, 2000, a total of 1,116,039 Common Shares of the Corporation were held
by interested parties, their affiliates and associates, representing 12.5% of
the total outstanding at such date.

In anticipation of shareholder approval of the foregoing increase in the number
of Common Shares reserved for issuance under the 1999 Stock Option Plan, on
October 20, 1999 the Board granted 10,000 options in aggregate at a price of
$7.50 per Common Share to an employee in satisfaction of a condition of his
employment.

In accordance with the rules of the TSE, these options cannot be exercised until
shareholders have approved the increase in the number of options available under
the 1999 Stock Option Plan described above.

VOTE REQUIRED FOR APPROVAL OF INCREASE IN NUMBER OF SHARES RESERVED FOR OPTIONS

The resolution approving the increase in the number of Common Shares reserved
for issuance under the 1999 Stock Option Plan from 272,543 to 372,543 requires
the affirmative vote in respect thereof of a majority of the votes cast by
holders of shares represented in person or by proxy, excluding any votes cast by
directors, officers and insiders of the Corporation who may participate in the
Plan, and their associates. Accordingly, the votes by the directors, officers
and insiders and their associates, representing approximately 1,116,039 votes,
will be excluded in counting the votes cast to approve the foregoing amendment
to the Plan.

THE BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE APPROVAL
OF THE INCREASE IN THE NUMBER OF COMMON SHARES RESERVED FOR ISSUANCE UNDER THE
1999 STOCK OPTION PLAN.

REPORTS REQUIRED BY SECTION 16(a)

Section 16(a) of the Securities Exchange Act of 1934 requires the Corporation's
directors and executive officers, and persons who own more than 10% of the
Corporation's Common Shares to file reports of ownership and changes in
ownership of the Corporation's Common Shares with the Securities and Exchange
Commission and any exchange on which the Corporation's Common Shares are traded.
Based solely on its review of the copies of Forms 3, 4 and 5 received by the
Corporation, or written representations from certain reporting persons that no
Form 5s were required for such persons, the Corporation believes that, during
the fiscal year ended December 31, 1999, all Section 16(a) filing requirements
applicable to its officers, directors and 10% shareholders were complied with.

                                  REPORT OF THE
                   EXECUTIVE COMPENSATION / PENSION COMMITTEE

The following is the report of the Executive Compensation / Pension Committee of
the Corporation describing the compensation policies and rationale with respect
to compensation paid to executive officers for the year ended December 31, 1999.
The information contained in the report shall not be deemed to be "soliciting
material" or to be "filed" with the Securities and Exchange Commission nor shall
such information be incorporated by reference into any future filing under the
Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as
amended, except to the extent that the Corporation specifically incorporates it
by reference into such filing.

The Corporation applies a consistent philosophy to compensation for all
employees. This philosophy is based on the premise that the achievements of the
Corporation result from the co-ordinated efforts of all individuals working
toward common objectives. The Corporation strives to achieve those objectives
through teamwork that is focused on meeting the expectations of customers and
shareholders.

COMPENSATION PHILOSOPHY

The goals of the compensation program are to align compensation with business
objectives and performance, and to enable the Corporation to attract, retain and
reward executive officers who contribute to the long term success of the
Corporation. The Corporation's compensation program for executive officers,
including the President and Chief Executive Officer (CEO), is based on the same
five principles applicable to compensation decisions for all employees of the
Corporation:



                                                             ZEMEX CORPORATION 9
   12

o     The Corporation pays competitively. The Corporation is committed to
      providing a pay program that helps attract and retain the best people in
      the industry. To ensure that pay is competitive, the Corporation regularly
      compares its pay practices with those of other leading companies and sets
      its pay parameters based on this review.

o     The Corporation pays for relative sustained performance. Executive
      officers are rewarded based upon corporate performance, business unit
      performance and individual performance. Corporate performance and business
      unit performance are evaluated by reviewing the extent to which strategic
      and business plan goals are met, including such factors as operating
      profit, performance relative to competitors, new product introductions and
      execution of long term strategy. Individual performance is evaluated by
      reviewing organizational and management development progress against set
      objectives and the degree to which teamwork and Corporation values are
      fostered.

o     The Corporation strives for fairness in the administration of pay.

o     The Corporation strives to achieve a balance of the compensation paid to a
      particular individual and the compensation paid to other executives both
      inside the Corporation and at comparable companies.

o     The Corporation believes that employees should understand how the
      performance evaluation and pay administration process works.

The process of assessing performance is as follows:

o     At the beginning of the performance cycle, the evaluating manager sets
      objectives and key goals and submits these for review by the head of that
      division and the President and CEO of the Corporation.

o     The evaluating manager gives the employee ongoing feedback on performance.

o     At the end of the performance cycle, the manager evaluates the employee's
      accomplishment of objectives / key goals.

o     The manager compares the results to the results of peers within the
      operating unit.

o     The evaluating manager communicates the comparative results to the
      employee.

o     The comparative results affects decisions on salary, bonuses and stock
      options.

COMPENSATION

The Corporation has had a history of using a simple total compensation program
that consists of cash and, since 1990, equity-based compensation. Having a
compensation program that allows the Corporation to successfully attract and
retain key employees permits it to provide useful products and services to
customers, enhance shareholder value, motivate technological innovation, foster
teamwork, and adequately reward employees. The compensation vehicles are:

o        CASH-BASED COMPENSATION
         Salary: The Corporation sets base salary for employees by reviewing the
         aggregate of base salary and annual bonus for competitive positions in
         the market.

o        EQUITY-BASED COMPENSATION
         Stock Option Program: The purpose of this program is to provide
         additional incentives to employees to work to maximize shareholder
         value. The option program also utilizes vesting periods to encourage
         key employees to continue in the employ of the Corporation.

o        BONUS PROGRAM
         The Corporation maintains a bonus program for certain key employees
         which is specifically designed to grant greater compensation to those
         key employees to recognize their performance in the plan year.


1999 PERFORMANCE

At the beginning of fiscal 1999, the Executive Compensation / Pension Committee
reviewed performance objectives for the Corporation. Performance relative to
these objectives was the basis for determining the 1999 bonus of the President
and CEO.

Similarly, 1999 performance goals for the other Named Officers were approved by
the President and CEO at the beginning of the year. Performance measures and
goals were similar to those of the President and CEO. Their performance for 1999
was evaluated by the President and CEO and bonuses were awarded based on this
evaluation.

(1)   On February 18, 1997, Mr. Goodwin and Mr. Hogan were granted options for
      10,000 and 15,000 Common Shares, respectively, at an exercise price of
      $7.25. On April 21, 1997, Mr. Gillespie was granted options for 25,000
      Common Shares at an exercise price of $7.00. On February 19, 1998, Mr.
      Gillespie was granted options for 25,000 Common Shares at an exercise
      price of $7.875. On May 15, 1998, Mr. Lister, Mr. Goodwin, Mr. Palmiere,
      Mr. Hogan and Mr. Gillespie were granted options for 80,000, 25,000,
      25,000, 25,000 and 25,000 Common Shares, respectively, at an exercise
      price of $10.1825. On May 26, 1999, Mr. Lister was granted stock options
      for 120,000 Common Shares at an exercise price of $6.2625; these options
      replaced the options to purchase 120,000 Common Shares at an exercise
      price of $5.50 that had been previously granted to Mr. Lister and that
      expired on May 26, 1999.

(2)   Constitutes premiums for term life insurance exceeding amounts eligible to
      most employees, automobile benefits, memberships/dues, and employer
      matched contributions to a group registered retirement plan and an
      employee stock purchase plan. The Corporation has an employee stock
      purchase plan whereby employees may elect to invest up to 10% of their
      earnings and the Corporation matches funding for the purchase of the
      Corporation's Common Shares. Common Shares purchased under this plan are
      held for a one-year vesting period. In connection with the plan, amounts
      shown for Mr. Lister include $25,200 in each of 1999, 1998, and 1997 with
      respect to





                                                            ZEMEX CORPORATION 12

      benefits derived from participation in the plan. Amounts shown for Mr.
      Goodwin include plan benefits of $18,744, $18,120, and $16,248 in 1999,
      1998 and 1997, respectively. Amounts shown for Mr. Hogan include plan
      benefits of $13,323, $13,250, and $13,000 for 1999, 1998, and 1997,
      respectively. Amounts shown for Mr. Gillespie include plan benefits of
      $9,600, $4,200, and $3,150 in 1999, 1998 and 1997, respectively. Amounts
      shown for Mr. Lister do not include imputed interest of $87,465, $83,152,
      and $65,596, in 1999, 1998, and 1997, respectively, on a loan Mr. Lister
      received under the Corporation's Key Executive Stock Purchase Plan. The
      Corporation does not reimburse Mr. Lister for any tax consequences arising
      from this loan. (See Note 9 Principal Shareholders and Security Ownership
      of Management.)

(3)   Includes benefit from the exercise of stock options. On May 26, 1999, Mr.
      Lister exercised stock options for 120,000 Common Shares at $5.50; these
      options were expiring May 26, 1999. Pursuant to its stock option plan, the
      Corporation may determine the form of consideration (including cash,
      Common Shares, or any combination of cash and Common Shares), which may be
      given to a person exercising options. Mr. Lister was issued 14,610 Common
      Shares, which was the share equivalent to the cash value of the exercise.
      The cash value of the exercise was calculated by multiplying the number of
      options by the difference between the exercise price of $5.50 and the fair
      market value of the Common Shares of $6.2625, (the average of the closing
      prices of the Corporation's Common Shares for the five days preceding the
      expiration date). Similarly, on November 8, 1999, Mr. Palmiere exercised
      stock options for 60,000 Common Shares at $7.125; these options were
      expiring November 8, 1999. Mr. Palmiere realized a cash value of $60,000
      from the exercise, calculated by multiplying the number of options by the
      difference between the exercise price of $7.125 and the fair market value
      of the Common Shares of $8.125, (the lower of the average of the closing
      prices of the Corporation's Common Shares for the five days preceding the
      expiration date and the closing price on the date of expiration).


OPTION EXERCISE AND YEAR-END VALUES TABLE

With respect to the Named Officers, the following table sets forth the number of
options exercised and the value realized upon exercise and the value of
outstanding options at December 31, 1999, using $8.375, the closing price of the
Common Shares on the New York Stock Exchange on December 31, 1999.

                              CORPORATE GOVERNANCE

The TSE has adopted guidelines for effective corporate governance (the "TSE
Guidelines"), addressing matters such as the constitution of, and functions to
be performed by, the Board and its committees. The TSE requires that each listed
corporation incorporated in Canada or a province of Canada disclose its approach
to corporate governance with reference to these guidelines on an annual basis.

BOARD MANDATE
The Corporation's Board is ultimately responsible for supervising the management
of the business and affairs of the Corporation and to act in the best interests
of the Corporation. The Board discharges its responsibility directly and through
its committees, which consist of an Audit Committee, a Corporate Governance
Committee, an Executive Committee, and an Executive Compensation / Pension
Committee. Specific responsibilities of the Board include reviewing and
approving the Corporation's (i) strategic and operating plans; (ii) corporate
objectives and goals applicable to the senior management of the Corporation and
significant operational and financial matters and providing direction on these
matters; and (iii) corporate governance practices and determining what, if any,
changes are necessary.

Currently the Board consists of eight persons, of which seven are unrelated:
Messrs. Carroll, Cohen, Donovan, Gillin, Lawson-Johnston, MacRae and vanden
Heuvel. Under the TSE Guidelines, an unrelated director is a director who is
independent of management and is free from any interest in any business or other
relationship which could, or could reasonably be perceived to, materially
interfere with the directors' ability to act with a view to the best interests
of the Corporation, other than interests and relationships arising from
shareholding.

Mr. Lister is a director and the President and Chief Executive Officer of the
Corporation. In the view of the Board, given the number of unrelated directors,
including the fact that the Chairman is not a member of management, the fact
that Mr. Lister is a member of the Board as well as senior management does not
impair the ability of the Board to act independently of management. The
Corporation believes that the investment of all shareholders in the Corporation
is fairly reflected in the composition of the Board.

The directors have considered the size of the board with a view to determining
its effectiveness and have concluded that the number of director is appropriate.

BOARD MEETINGS AND COMMITTEES

The Board met seven times during 1999. No director attended fewer than 75% of
the meetings of the Board and its committees held during the period in 1999.

The Corporation maintains standing Audit, Corporate Governance, Executive, and
Executive Compensation / Pension Committees.

Audit Committee
The Audit Committee, which met twice during 1999, is composed of John M. Donovan
(Chairman), Garth A.C. MacRae and William J. vanden Heuvel. The Audit Committee
reviews the financial reporting process of the Corporation on behalf of the
Board. In fulfilling its responsibility, the Audit Committee recommended to the
Board, subject to shareholder approval, the selection of Deloitte & Touche LLP
as the Corporation's independent auditors. During 1999, the Audit Committee met
with the Corporation's management and with representatives of Deloitte & Touche
LLP without the Corporation's management being present.

   19
Corporate Governance Committee
At the beginning of 1999, the Board established a Corporate Governance Committee
with the mandate of reviewing the Corporation's corporate governance practices
and to determine and report to the Board on what, if any, changes are necessary.
The Corporate Governance Committee is comprised of R. Peter Gillin (Chairman),
Paul A. Carroll, and William J. vanden Heuvel. Although the Corporation has a
Corporate Governance Committee, issues of corporate governance continue to be
discussed and decided at the Board level. The Board continues to have
responsibility for, among other things, nominating new directors, reviewing the
adequacy and form of compensation of directors, providing orientation and
education programs for new recruits to the Board, and approving requests of
directors to engage outside advisors at the expense of the Corporation.

Executive Committee
The Executive Committee, whose members include Peter O. Lawson-Johnston, John M.
Donovan, Garth A.C. MacRae and Richard L. Lister (Chairman), met four times
during 1999. The purpose of the Executive Committee is to act on behalf of the
Board and to authorize and approve major capital expenditures, which are
subsequently ratified by the full Board.

Executive Compensation / Pension Committee
The Executive Compensation / Pension Committee, whose members include Paul A.
Carroll (Chairman), Peter O. Lawson-Johnston and John M. Donovan, met three
times during 1999. The Executive Compensation / Pension Committee sets policies
and guidelines with respect to compensation and pensions.

BOARD PERFORMANCE

Although the Board did not formally assess the effectiveness of the Board of
Directors in 1999, the Board continually assesses the performance of management
and the Corporation. In that regard, the Board believes that management and the
Corporation performed well in fiscal 1999.

SHAREHOLDER FEEDBACK

All shareholder or investment community inquiries are directed to the Corporate
Secretary and Assistant Treasurer. Shareholder inquiries are responded to
promptly by the appropriate individual at the Corporation. In order to be
considered for inclusion in the Corporation's proxy statement for the 2001
Annual Meeting of Shareholders, proposals from shareholders must be received by
the Corporation on or before December 1, 2000. Such proposals should be
addressed to the Corporate Secretary and Assistant Treasurer, Zemex Corporation,
Canada Trust Tower, BCE Place, 161 Bay Street, Suite 3750, Toronto, Ontario, M5J
2S1.

EXPECTATIONS OF MANAGEMENT

The Board believes it is critical that management of the Corporation provides
complete and accurate information with respect to the business and affairs of
the Corporation and an analysis of the industries in which the Corporation
operates. To date the Board believes management has provided detailed quarterly
information, which has allowed the Board to be effective in supervising the
business and affairs of the Corporation.

BOARD APPROVAL

The Board has no formal policy setting out what specific matters must be brought
by management to the Board for approval; however, there is a clear understanding
between management and the Board through historical Board practice and accepted
legal practice that all transactions or matters of a material nature must be
presented by management for approval by the Board. It has been the experience to
date of the Board that they have been kept well informed as to the business and
affairs of the Corporation and that the matters which have been brought forward
to the Board for approval have been appropriate.


PERFORMANCE GRAPH

The performance graph compares the performance of the Corporation's Common
Shares to the Dow Jones Industrial Average Index and the Dow Jones Basic
Materials Average Index over the past five-year period. The graph assumes that
the value of the investment in the Corporation's Common Shares and each index
was $100 at December 31, 1994 and that all dividends were reinvested. As a
diversified producer of industrial minerals and specialty products, many of the
companies with which the Corporation competes are private and peer group
comparative data is not available.
