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.

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.

It is also the world's thirdlargest producer of LNG and is forecast to be the world leader by 2020. Reduction of iron ore to reduced iron form adds value and provides more compact products, which reduces shipping costs. The specific iron content of the direct reduced iron is a function of the iron content of the iron ore.

Production of DRI using iron ore in lump form may seem to be a viable alternative for already beneficiated iron ore provided the base material is of highgrade quality. Furthermore, the use of lowgrade iron ore could better be encouraged provided a more efficient coalbased direct reduction DR process is employed. The treatment of lowgrade ...

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.
