Designing Process for Beneficiation of Low Grade Iron Ore Samples from Orissa

The paper deals with the results of characterization and beneficiation studies carried on low grade iron ore samples from Orissa. Beneficiation of the two individual samples and their compostite based on gravity and magnetic separation techniques resulted in products with varying yield and grade of the products.The results of laboratory studies were validated through pilot scale trials. Based on the studies undertaken process was designed for bene-ficiation of the composite sample, comprising 60% S I and 40% S2, to a high grade product assaying over 65% Fe. Detailed material balance for the designed process was also undertaken
