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 ...

DRI: This iron production process directly reduces iron ore in solidstate with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gasbased DRI) or coal (coalbased DRI) called syngas, a mixture of H 2 and CO. Although DRI production is more energy efficient than pig iron production from BF ...

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.

This is equivalent to about 2 billion tonnes and 1 billion tonnes iron ore, respectively. The incremental iron ore demand of about 440 mt from increased DRI production could be met, assuming adequate replacement of depleted reserves. However, from the qualitative perspective, there is a potentially serious problem. This is the iron ore challenge!

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.
