Iron, Chemical Element
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. Iron produced by this method is about 91 to 92 percent pure. The main impurity left is carbon from the coke used in the furnace.
