36. Why is sulphide ore of copper heated in a furnace after mixing with silica? Solution Sulphide ore of copper is heated in a furnace after mixing with silica because the iron impurities present in the ore can form slag with silica and will be easily removed. The copper is produced as copper matte. FeO + SiO2 FeSiO3(slag) 37.
