Pig iron is remelted and cast into moulds, this is known as cast iron. Wrought Iron This is the purest form of iron. it is obtained by oxidising the impurities of cast iron by heating with haematite. Carbon is oxidised to CO. Si, P and Mn are also oxidised and form a slag which is removed by passing through rollers. Wrought iron is 99.5% pure.
