KINETICS OF IRON ORE REDUCTION BY COAL AND CHARCOAL . iron, the impurities must be removed by stone reduction. The possible ways of iron ore reduction: Industrially iron is produced from iron ores, principally hematite (Fe 2O3), magnetite (Fe 3O4) by a carbothermic reaction that is reduction with carbon, in a blast furnace at temperature about 1600 OC.

Reduction of iron ore with coal by microwave heating (Book ...

The reduction of iron ore with coal by microwave heating produces a pure, dust-free, and high Btu flue gas that can be used in related thermal operations. Depending upon the purity, the reduced iron product could be fed directly to electric arc furnaces for melting.

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
