(A) During the extraction of copper,the final step involves the Bessemerization of copper matte $(Cu_2S + FeS)$.In this process,the reaction $2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$ occurs.Subsequently,$Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$ takes place.The $SO_2$ gas produced escapes from the molten copper as it solidifies,creating bubbles on the surface,which are known as 'blister copper'.
