Extractive Metallurgy of Copper
The most common ore used in 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.

Copper Metallurgy
Primary copper sulfide minerals such as chalcopyrite and bornite are leached slowly, with poor result. The leach solution contains only 1–6 g/L of copper with impurity elements such as iron, aluminum, zinc, calcium, and magnesium; existing, solvent extraction is usually used to extract and enrich copper from the solution. Extraction
