Horsehead Starts Up New Tennessee Kiln on Schedule

MONACA, Pa., Jan. 2 /PRNewswire-FirstCall/ -- Horsehead Holding Corp.
(Nasdaq: ZINC), a leading U.S. producer of zinc metal and zinc oxide and among
the world's largest recyclers of electric arc furnace (EAF) dust and other
zinc-bearing materials, announced today that its wholly-owned subsidiary,
Horsehead Corporation, has started up a second Waelz kiln at its Rockwood,
Tenn., location. The Waelz kiln utilizes Horsehead's proprietary know-how
for recycling EAF dust.
Horsehead broke ground at the Rockwood facility in December 2006 with
expectations to be operational by the end of 2007. The new kiln will double
the current EAF dust processing capacity at that location. "We are excited
about this expansion which will allow us to grow our EAF dust recycling
business by 15 percent by increasing our service to the growing mini-mill
steel industry," said Jim Hensler, Horsehead's President & CEO. The new zinc
units from this new kiln will feed Horsehead's smelting operation in its
Monaca, Pa., facility, which in turn will produce more zinc products. The
addition of the new kiln will also create 10 additional jobs.
Horsehead Holding Corp. (Nasdaq: ZINC) is a leading U.S. producer of
specialty zinc and zinc-based products. Headquartered in Monaca, PA, Horsehead
employs over 1,000 people and operates six facilities throughout the U.S.
