DRI and HBI are usually made from highgrade iron ore pellets typically reduced by gas to provide a highlymetallized raw material for both electric arc furnaces and traditional blast furnaces. According to USbased DRI technologist Midrex Technologies, HBI, which is metallized beyond 90%, needs only to be melted.

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using noncoking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

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 ...

Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

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.
