Iron ore is a basic raw material used for pig iron production in the blast furnace. The ore burden preparation plays a very vital role in the improvement of the blast furnace productivity. Ore processing has been employed to the ore burden prepa-ration by way of sizing the ore and beneficiation. For better blast furnace produc-
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. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
