Extraction of copper ore

The extraction process involves the following steps: (i) Condensation of ore: Only 2≈3% Copper (Cu) is present in copper pyrites (CuFeS 2 ). After concentrating it by oil-froth floatation process, the amount of Cu will be 20≈30%. copper pyrites) and similar sulphide ores are the commonest ores of copper
