How is copper extracted from its sulphide ore? Explain the …
Copper is found as Cu 2S in nature. It can be formed just heating it in air. 2Cu 2S+3O 2 Heat 2Cu 2O+SO 2↑ 2Cu 2O+Cu 2S Heat 6Cu+SO 2↑ Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode.
