  • Why is the extraction of copper from pyrites more

    The Gibbs free energy of formationf 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 s2Cu s + CO g. Hence, the extraction of copper from its pyrite
