(C) In the extraction of copper,the copper sulfide $(Cu_2S)$ is partially roasted to form copper oxide $(Cu_2O)$.$2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$The remaining copper sulfide then reacts with the copper oxide to produce metallic copper,a process known as self-reduction.$2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$
