12. Stage 4 – Removal of Impurities The original ore contains silica (SiO 2, silicon dioxide). These react with limestone to form a molten slag of e.g. calcium silicate in 2 stages CaCO 3 CaO + CO 2 CaO + SiO 2 CaSiO 3 The molten slag forms a layer above the more dense molten iron and can be separately, and regularly, drained away.
