    Preparation of Wrought Iron. This is done by heating cast iron with haematite (Fe 2 O 3) which oxidizes C to CO, S to SO 2, Si to SiO 2, P to P 4 O 10 and Mn to MnO. Fe 2 O 3 + 3C → 2Fe + 3CO. Where CO and SO 2 escape, manganous oxides (MnO) and Silica (SiO 2) combine to form slag.. MnO + SiO 2 → MnSiO 3. Similarly phosphorous pentoxide combines with haematite to
