Iron Essential Chemical Industry
Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale. These are linked to locations where there is a plentiful supply of natural gas or lowgrade coal.
