(C) In the extraction of copper from its sulphide ore,the metal is formed by the self-reduction of $Cu_2O$ with $Cu_2S$. The sulphide ore of copper is heated in air until a part is converted to oxide $(Cu_2O)$. Then,upon further heating in the absence of air,the oxide reacts with the remaining unchanged sulphide $(Cu_2S)$ to produce metallic copper. The chemical reactions involved are: $2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$ $2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$
