    In the first stage, iron ore is heated with limestone and coke (pure carbon) in a blast furnace. A blast furnace is a very large oven in which the temperature may reach 1,500 ° C (2,700 ° F). In the blast furnace, coke removes oxygen from iron ore: The limestone removes impurities in the iron ore.
