copper extracted from copper pyrites

Copper is extracted from copper pyrites by - Tardigrade

Solution: The formula of copper pyrites is C u F e S 2. In auto reduction, the sulphide ores of the metals which are less electropositive like H g, P b and C u are heated in the air so as to convert a part of it to its oxides. These oxides then react with the remaining sulphide ore in the absence of air, to give the metal and sulphur dioxide.

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).
