The use of a gaseous reductant to convert goethite to magnetite in low grade iron ore fines offers additional advantages over conventional reductants such as coal or coke. For example, traditional ironmaking processes such as the blast furnace emit large volumes of CO 2 contributing significantly to the global carbon budget.

Due to the depleting reserves of DSO ores and increasing development of low-grade hematite and magnetite deposits the need for iron ore beneficiation is increasing. Even the DSO ores are requiring a higher level of processing as the depth of existing mines is increasing below water table where ores are wet and more sticky which creates challenges for conventional crushing and screening.
