  • 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 2Therefore, 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.
