Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
Compared to other steel plants the Qatar Steel's most significant advantage is that its production is based on DRI which uses clean raw material. It employs various methods of recycling and re-using production waste, basing its production process on the utilization of clean raw materials and, steel making technology that is the lowest producer ...
Year 2000 saw the erection and commissioning of a 2 MTPA blast furnace at the Dolvi steel complex. Sponge iron capacity was increased from 1.2 MTPA to 1.4 MTPA in the year 2003. Year 2004 saw the increase in capacity of Hot rolled coil from 1.5 MTPA to 2.4 MTPA and Sponge iron from 1.4 MTPA to 1.6 MTPA.
Cleveland-Cliffs manages and operates four iron ore mines in Minnesota and two mines in Michigan, one of which, the Empire Mine, has been indefinitely idled. [3] These mines produce various grades of iron ore pellets, including standard and fluxed, for use in blast furnaces as part of the steelmaking process as well as Direct Reduced (DR) grade pellets for use in direct reduced iron (DRI ...
