It is very easy to reduce iron ore at a temperature well below its melting point and produce a more-or-less-pure metal which can be used directly for implements, tools, or machines. This simplicity has been the cause of much money loss by persons who were so satisfied with the successful operation of a process that they paid all too little attention to the …

DRI is preferred in India because of 1.Small scale of production. 2.Access to iron ore. 3.Paucity of coking coal in India. Between 2004-05 and 2009-10, the DRI production in India has increased by 24% as compared to only 8% for steel per annum. For steel produced through the coking coal route, the production growth is only 5.5%.

Iron ore, when subjected to reducing gases at a temperature suitable for reduction of the oxide but not high enough to melt the ore or metal formed, is converted into metallic iron. The product, being the original piece of iron oxide minus its oxygen, is sponge-like in appearance when viewed under a magnifying glass, and hence is called 'sponge …
