The total resources of iron ore (hematite) in the state as on 1.4.2010 are estimated at 5930 million tonnes (IBM Mineral Year Book 2014) as against 3,789 million tonnes inventoried by IBM in 2005. As per the compendium of mineral resources of Orissa, Govt of Orissa (2009) the total resource was 5231 million tonnes.
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

He said the company will be setting up two iron ore beneficiation plants at an area spread over 500 acres at Waddarahalli and 450 acres at Nandibanda villages near Hospet in Bellary district. MSPL proposes to use Banded Haematite Quartzite (BHQ), which is low grade iron ore with 35-37 per cent iron content, for extraction of iron ore fines.
To utilize the large amount of iron-ore fines produced during mechanized mining and in the ore-handling plants, the provision of sintering facilities has been proposed in almost all the steel plants. Generally the fines have higher alumina and silica contents than the lumpy ore. Sinter made from such aluminous fines using coke breeze
