  • Why Is The Extraction Of Copper From Pyrites -

    The Gibbs free energy of formation f G of Cu 2 S is less than that of H 2 S and CS 2.Therefore 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 .
