Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal Many ores are suitable for direct reductionThe MIDREX Process - Direct Reduction Ironmaking Technologies,In the early days of direct reduction, there was a clearly discernible difference between iron oxide pellets intended for blast furnace use (BF-grade pellets) and those used to make DRI to feed an EAFDirect Reduced Iron | Industrial Efficiency Technology ,Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction
