The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon.

During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3), and other nonferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it easier to separate them from the iron and recover them. This recovered substance is slag.
