Direct reduced iron  </h2>(*)<p>Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at a high temperature of 800 to 1200 176;C in the presence of a reducing gas called syngas which is a mixture of hydrogen and carbon monoxide.

GASIFICATION AND THE MIDREX? DIRECT REDUCTION

The production of direct reduced iron (DRI), a basic raw material for making steel, is concentrated in a few countries in the Middle East and Latin America. One primary reason is that natural gas, the main fuel source for most DRI processes, is too costly in many of the steel making regions of the world.

Direct Reduced Iron (DRI) is created by heating iron ore in a steel shaft with natural gas, below the melting point. The resulting iron pellets can be used as a replacement or enhancement of scrap and pig iron. DRI should price comparably to merchant pig iron as well as higher quality scrap grades.

Direct reduction (DR) This is any process in which iron is extracted from ore at a temperature below the melting points of the materials involved. Gangue remains in the spongelike product, known as directreduced iron, or DRI, and must be removed in a subsequent steelmaking process. Only highgrade ores and pellets made from superconcentrates (66 percent iron) are therefore really suitable for DR iron
