Vedclass · Answer

(B) During the extraction of copper from copper pyrites $(CuFeS_2)$,the ore is roasted to remove sulfur and then smelted in a blast furnace. In the furnace,iron oxide $(FeO)$ is formed as an impurity. Silica $(SiO_2)$ is added as a flux to remove this impurity. $FeO + SiO_2 \rightarrow FeSiO_3$ (slag). Thus,the slag formed is iron silicate $(FeSiO_3)$.

What does the slag obtained during the extraction of copper mainly consist of?
