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.

Abstract Beneficiation of high alumina iron ore fines from Noamundi, India is studied for producing sinter/ pellet grade concentrate. The iron ore fine sample has a feed grade of 59.77%Fe, %4.71SiO 2, and % 5.89Al 2 O 3 with % 5.53 of LOI (Loss on Ignition).

Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply. Hence, the scenario is steadily shifting towards the use of low grade iron ores and slimes which are stock piled in the mine's sites for years.
