Iron ore, in pellet or lump form or both, is introduced to the MIDREX reduction shaft. As the iron ore descends through the furnace, the reformed reducing gas reacts with the Fe 2 O 3 in the iron ore and converts it to DRI, leaving H 2 O and CO 2 as offgas (Kolbeinsen 2010).

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.

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.

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.
