DetailsThis is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.
