Uses of Iron
The conventional method of extracting iron from haematite is by crushing it. The ore is placed on top of a blast furnace with a carbon source such as coke or calcium carbonate (limestone). Carbon monoxide is produced when coke is burned in the furnace. The iron ore is reduced to iron by carbon monoxide. At this point, the iron is liquid.
