Extractive Metallurgy of Copper - Meaning, Method and

The most common ore used in the copper extraction is Chalcopyrite (CuFeS 2), also recognized as Copper Pyrites and other such sulfides. The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible. The concentration of ore is required, and the Froth Flotation method is used for this process.
