Notes On Extraction Of Iron From Its Oxides Cbse Class

Pig iron is melted with scrap iron and coke in the presence of hot air to form cast iron, which contains only 3 carbon. Cast iron is heated in a reverberatory furnace lined with haematite, which oxidises carbon to carbon monoxide to get wrought iron or malleable iron, the purest form of iron.
