Zinc. Zinc concentrate is produced by separating the ore, which may contain as little as 2% zinc, from waste rock by crushing and flotation, a process normally performed at the mining site.
Millions of tonnes of low grade ore and copper rich tailings await the development of an efficient and economic bioleach process for chalcopyrite (CuFeS 2).The bioleaching of chalcopyrite in situ and in dumps is a practical option only because the low and slow recoveries are countered by the low processing costs (Schnell, 1997).Not surprisingly, the bioleaching of chalcopyrite, both the most
