Other projects such as Primetals' HYFOR and Boston Metal's application involve potentially bypassing pelletizing and DRI by directly reducing iron ore fines and concentrates into metallic iron for steelmaking. These remain electricity intensive, despite the energy saving potential and less pressure on hydrogen supplies.

DRI fines, generated during its manufacture and handling, generate high content of fines in the size fraction less than 2 mm. It has iron content above 80%. It is difficult to directly use such iron-rich material in the primary steel making process, without agglomeration. At JSW Steel Vijayanagar, around 50 to 70 tons per day of DRI fines …
