    In actual process, the ore is heated in a reverberatory furnace after mixing with silica. In the furnace, iron oxide ‘slags of’ as iron silicate and copper is produced in the form of copper matte. This contains Cu 2 S and FeS. FeO + SiO 2 → FeSiO 3 (Slag) Copper matte is then charged into silica lined convertor.
