Iron Production. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

· Production of DRI using iron ore in lump form may seem to be a viable alternative for already beneficiated iron ore provided the base material is of high-grade quality. Furthermore, the use of low-grade iron ore could better be encouraged provided a more efficient coal-based direct reduction DR process is employed.
