Vedclass · Answer

(C) The correct answer is $C$. During the extraction of copper from copper glance $(Cu_2S)$,the ore is partially roasted to form copper$(I)$ oxide $(Cu_2O)$. $2Cu_2S + 3O_2 	o 2Cu_2O + 2SO_2$ Subsequently,the remaining $Cu_2S$ reacts with the formed $Cu_2O$ to produce metallic copper. This process is known as self-reduction or auto-reduction. $2Cu_2O + Cu_2S 	o 6Cu + SO_2$
