When heated to 1250–1400 °C, the iron oxides are reduced to form metallic sponge iron, and the other mineral components form a slag phase. Fast reduction kinetics is achievable because of the close proximity of the carbon and iron oxide particles. Depending on the raw materials, reduction can be complete in as little as 10 min at 1300 °C.
