This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.
· The high copper grade in the Igarapé Bahia (Brazil) gold-copper ore restricts the direct application of the classical cyanidation process. Copper oxide and sulfide minerals react with cyanides in solution, causing high leach-reagent consumption, raising processing costs and decreasing gold recovery. According to studies, a feasible solution would be to pretreat the ore to remove copper ...
copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.
