All effective methods of direct reduction actually use the same process: rich iron ore (fine concentrate or pellets) is reduced by a special gas mixture up to the iron content of 85-90%. This explains why the production of direct-reduced iron is mainly concentrated in countries with large reserves of oil (oilwell gas), natural gas and iron ore, as well as limited scrap resources.

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. Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF) steel plant. DRI can be either hot or cold charged to ...

The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.. Sponge iron and pig iron are different forms of iron that we can produce from iron ores that occurs naturally under the surface of the earth.

Sponge iron is also known as Direct Reduced Iron (DRI). Direct reduction, is an alternative route of iron making has been developed to overcome some of these difficulties of conventional blast furnaces. DRI is successfully manufactured through either gas or coal-based technology. Iron ore is reduced in solid state at 800-1050 c either by reducing gas (H2+CO) or coal. The direct reduction ...
