Vedclass · Answer

(C) In the smelting process of copper extraction,the roasted ore (containing $Cu_2S$ and $FeS$) is mixed with silica $(SiO_2)$ and heated in a blast furnace. $1$. $FeS$ is oxidized to $FeO$: $2FeS + 3\,O_2 	o 2\,FeO + 2\,SO_2 \uparrow$. $2$. $FeO$ reacts with silica to form slag: $FeO + SiO_2 	o FeSiO_3$. $3$. If any $Cu_2O$ is formed,it reacts with $FeS$ to form $Cu_2S$: $Cu_2O + FeS 	o Cu_2S + FeO$. Option $C$ represents the partial roasting reaction,which occurs during the roasting stage,not the smelting stage,as smelting primarily involves the formation of matte $(Cu_2S + FeS)$ and slag $(FeSiO_3)$.
