  • Why is the extraction of copper from pyrites more

    The Gibbs free energy of formation (Δ 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
