Clean Iron Production Through Direct Reduction Of Mineral

2 days ago 1.Introduction. Cleaner production is a vital preventative environmental protection initiative and is thus an issue of global concern. In the context of the iron- and steel industry, cleaner production is dependent to a very great extent on the possibilities that can be found for reducing CO 2 emissions. The iron and steel industry is a major greenhouse gas emitter and currently responsible ...

The Direct Reduction (DR) route is an alternative iron making route, which utilizes coal to reduce the iron ore. At Vanderbijlpark Works, six rotary kilns are used to heat iron ore, coal and additives to produce sponge iron, which is then utilized in an electric arc furnace or Basic Oxygen Furnace.

Nov 05, 2021 Further alternatives to reduce the environmental impact due to carbon emissions include the adoption of the direct reduced iron (DRI), which is also called iron sponge. DRI is produced from the reaction between iron oxides at the solid state (below the fusion temperature of pure iron, 1535 C), hydrocarbon gases, and/or carbon-bearing materials.

Directreduced Iron An Overview Sciencedirect Topics

Jan 05, 2012 Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of natural gas (e.g., Mexico produces virtually
