Vedclass · Answer

(B) During the extraction of copper from copper pyrites $(CuFeS_2)$,the ore is roasted to remove sulfur and then smelted.Iron present in the ore is oxidized to $FeO$,which then reacts with the added flux,silica $(SiO_2)$,to form a fusible slag,iron $(II)$ silicate $(FeSiO_3)$.The chemical reaction is:$2CuFeS_2 + 2SiO_2 + 3O_2 \rightarrow Cu_2S + 2FeSiO_3 + 2SO_2$Thus,iron is removed as $FeSiO_3$.
