Vedclass · Answer

(C) In the extraction of copper,the Bessemer converter is used for the conversion of copper matte $(Cu_2S + FeS)$ into blister copper. The reaction $2CuFeS_2 + O_2 	o Cu_2S + 2FeS + SO_2$ is a part of the roasting process,which occurs in a reverberatory furnace,not in the Bessemer converter. In the Bessemer converter,the following reactions occur: $2FeS + 3O_2 	o 2FeO + 2SO_2$ $FeO + SiO_2 	o FeSiO_3$ (Slag formation) $2Cu_2S + 3O_2 	o 2Cu_2O + 2SO_2$ $2Cu_2O + Cu_2S 	o 6Cu + SO_2$ Therefore,option $C$ is the correct answer.
