iron ore resources have become a national priority. As per the recent national steel policy, our country will be producing about 110 million tons of steel per annum by 2020 requiring around 42 million tons of iron ore. The iron ore exports are projected to a level of 114 million tones and it amounts to total production of 300 million tons by 2020.
The ore is available at extremely favorable costs, however, its use for the production of direct-reduced iron (DRI) in a process route that includes beneficiation, pelletizing, DRI production and steelmaking still had to be carefully investigated in terms of technical and economic feasibility.
