Extraction Of Copper | Mining, Concentration, Smelting ...

Copper Mining: The commonest ore used in the extraction of copper is CuFeS 2 also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.
