Management of toxic substances: base metals smelting sector

Base Metals Smelting is the production of cobalt, copper, lead, nickel and zinc through the use of pyrometallurgical, electrolytic or hydrometallurgical processes. Various co-product metals are produced, such as gold, silver, indium, germanium, cadmium, bismuth and selenium. Primary smelting and refining processes produce metals directly from ores, while secondary smelting and refining produces metals from scrap and process wastes.
