Vedclass · Answer

(B) In the Bessemer converter,the process of self-reduction (or auto-reduction) occurs to obtain metallic copper from copper matte.First,some $Cu_2S$ is oxidized to $Cu_2O$ by air: $2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$.Then,the remaining $Cu_2S$ reacts with the formed $Cu_2O$ to produce metallic copper: $2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$.This specific reaction of self-reduction is the primary process occurring in the Bessemer converter for copper extraction.
