Copper Extraction from Sulfide Ores - Latest Contents

OF COPPER This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk about 100,000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to …
