Vedclass · Answer

(C) In the extraction of copper,the Bessemer converter is used to convert copper matte $(Cu_2S + FeS)$ into blister copper.The reactions occurring in the Bessemer converter are:$1. \ 2FeS + 3O_2 \rightarrow 2FeO + 2SO_2$$2. \ FeO + SiO_2 \rightarrow FeSiO_3$ (Slag formation)$3. \ 2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$$4. \ 2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$The reaction $2CuFeS_2 + O_2 \rightarrow Cu_2S + 2FeS + SO_2$ occurs during the roasting process in a reverberatory furnace,not in the Bessemer converter.

Which of the following reaction$(s)$ do(es) not occur in Bessemer's converter?
