Direct Reduced Iron (DRI) is high in iron content and low in copper and other undesirable metals – tramp elements – and nitrogen content. It is used to make a broad range of steel products. Its physical and chemical characteristics make it desirable for use in the electric arc furnace (EAF), blast furnace (BF), and basic oxygen furnace (BOF).
In the last six years, worldwide DRI output has grown by almost 55 Mt, or approximately 75%, driven by a 136% increase in DRI production in India (mainly coal-based DRI), a …
The plant will have a capacity of 2.5 million metric tons of directly reduced iron (DRI), and is scheduled for completion by the end of 2026. The overall project remains subject to European Union approval under state aid provisions, as well as the final funding decision. Both are expected in the coming months.
This highly polluting method can be replaced with green hydrogen in a direct-reduced iron (DRI) facility, where the H2 reacts with the oxygen to produce steam (H2O) rather than carbon dioxide. In fact, hydrogen-based DRI is currently the only proven pathway of decarbonising steel production, when paired with an electric arc furnace …
Here in Lingen, we are already using iron ore from Namibia to optimize the process and the product," adds Köhne. This innovative process is made possible by the development of a proprietary gas-tight rotary kiln. Here the hydrogen reacts completely with the oxygen in the iron ore and converts it into elemental iron (direct reduced iron (DRI)).
Champion Iron announced in late April that it had approved an increase of $52 million to its initial budget of $10 million for the engineering and construction of its direct reduction pellet feed (DRPF) project at its Bloom Lake iron ore complex in Quebec. The project has an anticipated cost of $470.7 million and is expected to be completed …
In addition, direct reduced iron has a well-defined chemical composition when compared with steel scrap and has efficient melting properties in the electric arc furnace.
1. Introduction. Industrial-scale hydrogen-ironmaking, also known as direct reduction of iron (DRI) using hydrogen, is a process that aims to produce iron without the use of fossil fuels (Chevrier, 2020; van Vuuren et al., 2022; Tang et al., 2020; Wang et al., 2021; Ledari et al., 2023).This process has the potential to significantly reduce carbon …
Direct Reduced Iron (DRI) is a high-quality metallic product (~90% pure iron) produced by the direct reduction of iron oxide at a temperature below the fusion point of iron. It is primarily used in electric arc furnaces (EAF) but can also be used by blast furnaces and other iron and steelmaking applications.
DRI is a high-quality iron ore product that is used to make steel. It is produced by reducing iron ore with natural gas in a process called direct reduction. DRI is a cleaner and more efficient alternative to traditional blast furnace steelmaking, as it emits fewer greenhouse gases and consumes less energy.
1.1 Direct Reduced Iron Direct reduced iron is produced by the reduction of iron ore by carbon monoxide and hydrogen, as illustrated in simplified form in the equations below: Fe 2O 3 + 3CO → 2Fe + 3CO 2. Fe 2O 3 + 3H 2 → 2Fe + 3H 2O . There are several processes for direct reduction of iron ore, principally gas-based shaft furnaces
Green hydrogen made from new, renewable energy resources can be used to make fossil-free iron in modern direct-reduced iron (DRI) furnaces. Advocates …
In the field of extraction metallurgy, the direct reduction-grinding separation process is an effective technology, especially for the treatment of vanadium titanium magnetite and low-grade iron ores [1], [2], [3].Direct reduction is a process in which gaseous (H 2, CO) or solid reducing agents (coal, biomass) are used to reduce the …
Saudi Arabia has a large-scale project for direct reduced iron (DRI) pellet production to be newly set up in the coming years. The investment, a part of the Saudi Vision 2030 development strategy, aims to help steel producers in the region to secure their positions in terms of raw material supply and to eventually support their competitiveness …
This means, that all the gangue materials remain in the product sponge iron, called Direct Reduced Iron (DRI). Direct reduction processes can be classified by its kind of used reducing agent in gas-based processes and coal-based processes. Gas-based processes are shaft furnaces, retorts and fluidized beds.
The shaft furnace direct reduction-electric arc furnace (DR-EAF) route (Fig. 1) is the primary alternative to the BF-BOF route, which reduces lump ore/pellets to direct reduced iron (DRI) primarily using natural gas (NG), and further converts the DRI in an EAF. The DR-EAF route significantly reduced the consumption of coke and coal while ...

MIDREX Plants have produced a cumulative total of more than 1.39 billion tons of all forms of DRI (cold DRI, CDRI; hot DRI, HDRI; and hot briquetted iron, HBI) through the end of 2023. MIDREX Technology continued to account for ~80% of worldwide production of DRI by shaft furnaces in 2023.
As a result, direct reduced iron (DRI) production has taken over as the dominant ironmaking method and the electric arc furnace (EAF) in combination with a DRI plant has become the preferred steelmaking route. ... Midrex partners are highly regarded for their technical expertise, adherence to project schedules, and exceptional performance.
Regardless of the steelmaking route, there is a form of direct reduced iron (DRI) for every application. DRI is a premium ore-based metallic (OBM) raw material made by removing chemically-bound oxygen from iron …
