    The blast furnace is filled with iron ore, coke and limestone. A very hot blast of air is blown in, where it causes the coke to burn. The extreme heat makes the carbon react with iron ore, taking off the oxygen from iron oxides, and making carbon dioxide. The carbon dioxide is a gas and it leaves the mix.

    About half of the carbon in the coke combines with the oxygen from the iron ore to make CO2. The rest of the coke is burned in a blast of air in the blast furnace to provide the required high temperature; making more CO2. The resulting pig iron typically contains 2.5 4.5% carbon, making it relatively brittle and unsuitable for most uses.
