2.4. Reactions involved in the reduction of mill scale by coal. The solid-state direct reduction processes generally operate at a temperature below 1100 C to prevent the formation of any semi-solid phases. During the reduction process the iron oxides present in any type of iron ore or mill scale get reduced to metallic iron in the solid-state.
