Vedclass · Answer

(B) In the commercial extraction of copper from copper glance $(Cu_2S)$,the process is known as self-reduction or auto-reduction.First,the sulphide ore is partially roasted in air to form copper$(I)$ oxide:$Cu_2S + \frac{3}{2}O_2 	o Cu_2O + SO_2$Then,the remaining copper$(I)$ sulphide reacts with the copper$(I)$ oxide formed to produce metallic copper:$2Cu_2O + Cu_2S 	o 6Cu + SO_2$This is the major reaction in the Bessemer converter.
