ISO - ISO/TC 102 - Iron ore and direct reduced iron

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 (Al2O3, MnO, and SiO2 etc.), to the corresponding ...
