Extraction The extraction of copper also involves many steps The ore used for extraction is copper pyrites This ore is crushed concentrated and then heated in the presence of air During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulphide and cuprous sulphide

EXTRACTION OF COPPER On industrial scale copper is extracted from its sulphide ore known as copper pyrite CuFeS 2 by smelting method STEPS OF EXTRACTION For more details CLICK HERE Concentration Roasting Smelting Bessemerization

The Gibbs free energy of formation Δ f G of Cu 2 S is less than that of H 2 S and CS ore H 2 and C cannot reduce Cu 2 S to Cu On the other hand the Gibbs free energy of formation of Cu 2 O is greater than that of CO Hence C can reduce Cu 2 O to Cu C s Cu 2 O s → 2Cu s CO g Hence the extraction of copper from its pyrite ore is difficult than from its oxide ore
