Beneficiation is the process of separating iron ore from the gangue particles like alumina, silica. Increasing the iron ore demand, with the faster depletion of high grade iron ore, it is the time to use low grade iron ore slime as a feed stock rather leaves as a waste. Mainly coarser fraction is rich in iron content and finer fraction contained large amount of gangue.
