Vedclass · Answer

(C) In the extraction of copper,the roasted ore is mixed with silica $(SiO_2)$ and heated in a reverberatory furnace. Iron oxide $(FeO)$ reacts with silica to form iron silicate slag $(FeSiO_3)$,which is removed. The remaining mixture,known as copper matte,primarily consists of cuprous sulphide $(Cu_2S)$ and ferrous sulphide $(FeS)$. Thus,copper matte contains sulphides of copper $(I)$ and iron $(II)$.

When copper ore is mixed with silica in a reverberatory furnace,copper matte is produced. The copper matte contains . . . . . .
