The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore.

An electric-arc furnace. The electric- arc furnace (EAF) is a squat, cylindrical vessel made of heavy steel plates. It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof (see figure ). The shell diameter of a 10-, 100-, and 300-ton EAF is approximately 2.5, 6, and 9 metres.

The most common method is the blast furnace process. In this high-temperature furnace, iron ore is mixed with coke (a carbon-rich material) and limestone. The intense heat generated in the furnace reduces the iron ore to molten iron, which is then cast into molds called pigs, giving rise to the term "pig iron." Stage 3: Steelmaking
