Copper extraction froth flotation process

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

In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely
