The Bureau of Mines is developing a leach-electrolysis procedure to produce Special High Grade (SHG) zinc from sulfide concentrate without the generation of sulfure oxide gases. Chlorine-oxygen leaching of the concentrate yields zink chloride, which, after purification, is electrolyzed in a fused-salt cell to obtain molten zinc metal and chlorine gas for recycle.
