DRI plants don't need to be next to steelmakers, as usually occurs at present, they said. Andrew Forrest, chairman and founder of Australia's Fortescue Future Industries Fortescue Metals Group—the world's fourthbiggest iron ore producer—said that the Pilbara, where FMG produces highgrade iron ore, could in the future become a hub for green hydrogenbased production of DRI, or sponge ...

The IIMA sees iron ore suppliers and DRIbased steel producers as interdependent components of the steel value chain which must cooperate closely to ensure iron ore of the right type and quality is available on a timely basis. "DRI and HBI are essential EAF steelmaking inputs, diluting residual metallic impurities in scrap, enabling production ...
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 ...
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 Reduced Iron Market Size, Share | Growth Report [2030]](/pmulwvg/12.jpg)
The global direct reduced iron market size was valued at USD billion in 2022 and is projected to grow from USD billion in 2023 to USD billion by 2030, exhibiting a CAGR of % during the forecast period. Direct reduced iron (DRI) is an iron ore in the form of pellets and lumps, also known as sponge iron.
Directreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ...
Typical ranges of DRI chemistry are 9094% total iron, 8389% metallic iron, % iron oxide, % carbon, % gangue, % phosphorus, and % sulfur. DRI normally has at least 90% of the oxygen removed, with the unreduced oxide present as wustite.
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 ...
By using DRI from higher grade iron ore feed, slag/steel ratios in the order of 100120 kg/t are possible for high DRI percentage in the charge (over 80%) with corresponding improvements on the abovementioned factors and the resulting economy (Roger Selin, 2021 private communication). In this paper, a slag volume of 100kg/t is used as a ...

The iron ore producer sees the steel industry moving through three stages, where operational efficiency is first targeted, including iron ore and energy optimization, before new technologies excluding green hydrogen are introduced in the blast furnace, and later a move to green DRI production.
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.
The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the noncoking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. See more information about the production of DRI .
