Direct reduced iron Wikipedia
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 or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
Pathways to decarbonisation episode two: steelmaking technology
In the DRI process, iron ore in the form of lump or pellets is reduced to metallic iron in the solid state unlike in the BF where the material is melted. Today, about 100 Mt of DRI is produced globally each year, with the majority of that using reformed natural gas (essentially splitting natural gas into hydrogen and carbon monoxide) to strip ...
Lack of highquality iron ore supply threatens steel's green push
One cleaner way to produce steel uses direct reduced iron, or DRI, in which ore is reduced with hydrogen and carbon monoxide. If global steelmaking follows a path to netzero emissions by 2050, demand for direct reduced, or DRgrade, iron ore could rise tenfold, IEEFA Energy Finance Analyst Simon Nicholas said.
