· In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Direct reduction can be defined as reduction in the solid state at O2 potentials which allow reduction of iron oxides, but not of other oxides (MnO, and SiO2 etc.), to the corresponding elements.

Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron.
