of the iron ore as well as iron and steel industry, and the way forward for meeting the set goals. 2 INDIAN IRON ORE RESOURCES India is endowed with large resources of iron ore, which is estimated to be about 28.52 billion tonnes of both hematite and magnetite ores. Table 1. Iron Ore Resources as on 01.04.2010 (In billion tonnes)(2) Ore Reserves
The government has so far auctioned over 186 mineral blocks in efforts to boost iron ore supply. However, iron ore accounts for only 52 of these. Around 85% of the blocks auctioned are of bulk minerals with 45% pertaining to ferrous minerals. Only four states — rich in iron ore and limestone deposits — account for 65% of mineral blocks ...

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand.
