  • Extracting copper. Extracting copper.

    Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99 pure copper.

    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).
