    Extraction of Copper from Copper pyrite | Grade 12

    The air oxidized Cu2S partially to Cu2O which then reduces remaining Cu2S to metallic copper. During this process no external reducing agent is used so it is an example of self-reduction. 2CuS + 3O2 → 2Cu2O + 2SO2. 2Cu2O + Cu2S → 6Cu + SO2. The reaction is highly exothermic and copper obtained is
