Vedclass · Answer

(B) During the extraction of copper from copper pyrites $(CuFeS_2)$,the ore is roasted to remove sulfur and convert iron into iron$(II)$ oxide $(FeO)$.$2CuFeS_2 + 4O_2 \rightarrow Cu_2S + 2FeO + 3SO_2$Silica $(SiO_2)$ is added as a flux to remove the $FeO$ impurity as slag.$FeO + SiO_2 \rightarrow FeSiO_3$ (slag)Therefore,the slag is mainly composed of $FeSiO_3$.

In the extraction of copper,the slag obtained is mainly composed of........
