(C) In the Bessemer converter,copper is extracted through a self-reduction process. The reactions involved are:$2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$$2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$These reactions occur because,at high temperatures,sulphur has a greater affinity for oxygen than copper does,allowing sulphur to remove oxygen from $Cu_2O$ to form $SO_2$ gas. Thus,copper has less affinity for oxygen than sulphur.
