Vedclass · Answer

(B) In the Bessemer converter,the molten matte $(Cu_2S + FeS)$ is subjected to oxidation. First,the remaining $FeS$ is oxidized to $FeO$,which then reacts with silica $(SiO_2)$ to form slag $(FeSiO_3)$. After the removal of iron,the remaining $Cu_2S$ undergoes self-reduction (autoreduction) by reacting with the $Cu_2O$ formed by the partial oxidation of $Cu_2S$. The chemical reaction is: $Cu_2S + 2Cu_2O \rightarrow 6Cu + SO_2$.

The reaction occurring in the final stage of the extraction of copper from copper pyrites in a Bessemer converter is:
