Vedclass · Answer

(B) In the extraction of copper from its sulphide ore,the ore is subjected to roasting,where some of it is oxidized to $Cu_{2}O$. This $Cu_{2}O$ then reacts with the remaining $Cu_{2}S$ (cuprous sulphide) to produce copper metal. The chemical equation for this self-reduction process is: $2Cu_{2}O + Cu_{2}S \longrightarrow 6Cu + SO_{2} \uparrow$ In this reaction,$Cu_{2}S$ acts as the reducing agent for $Cu_{2}O$.

In the extraction of copper from its sulphide ore,the metal is finally obtained by the reduction of cuprous oxide with
