In India, magnetic concentration is very effective method for the beneficiation of iron ore, nearly 90% of ores are concentrated by this method (Ryan 1991) (Table 1).

The previous works by IBM [ 1, 2 ], FIMI [ 3] and Sahoo et al. [ 4] on iron ore processing comprises of size reduction-sizing, washing—classification of fines, jigging of fine-chips, crushing-closed circuit grinding to liberate values followed by classification, gravity concentration, magnetic concentration, selective dispersion of gangue ...

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
