Vedclass · Answer

(C) Copper is extracted from its sulphide ore $(Cu_2S)$ primarily by the auto-reduction process.In this process,the ore is heated in a limited supply of air,where a portion of the sulphide ore is converted to oxide,which then reacts with the remaining sulphide ore to produce metallic copper.The chemical reaction is: $2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$Followed by: $2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$This method is known as auto-reduction because no external reducing agent like carbon or carbon monoxide is required.
