TORONTO, CANADA -- DECEMBER 8, 1999 -- ZEMEX CORPORATION (TSE, NYSE:ZMX)
announced today that it has retained the services of Banc of America Securities,
LLC to review methods and opportunities to maximize value for the shareholders
of Zemex.

Richard L. Lister, President and Chief Executive Officer of Zemex, commented,
"Although Zemex's financial performance and strength have improved significantly
since 1993, the Corporation's share price has failed to create a corresponding
increase in value for our shareholders. We have engaged Banc of America
Securities to assist us in identifying and evaluating alternatives that may be
available to the Corporation."

The Corporation also stated that it could give no assurance that any transaction
would result from these efforts.

Zemex Corporation is a diversified producer of industrial minerals, specialty
products and metal powders and, through its Alumitech division, reprocesses
aluminum drosses with patented zero discharge technology. Zemex currently
operates facilities across the United States and Canada. Its products are used
in a variety of commercial applications and are sold throughout the United
States, Canada and Europe.
