GSDK, is Korea´s newest facility dedicated to recovering zinc from the industrial waste stream. This plant recycles Electric Arc Furnace (EAF) steel dust utilizing the Waelz Kiln technology.
EAF dust, generated by steel mills contains zinc. GSDK’s brand-new facility specializes in the reclamation of zinc and other metals from this dust. GSDK’s main product is Waelz Oxide also known as Crude Zinc Oxide (CZO). This product is transformed into zinc oxide, zinc sulfate or zinc metal by zinc smelters. Our plant also produces Waelz Iron Product (WIP), an Iron Concentrate.
The GSDK recycling facility – located in Jeolla Province – will process more than 110,000 tons of EAF dust annually.
GSDK is part of the Promax Group, a widely diversified industrial group owner of Zinc Nacional with over 30 years of experience in the recycling of EAF steel dust. Zinc Nacional, founded in 1952, is a privately owned company dedicated to the production of zinc compounds and recycled paperboard.
