India possesses vast reserves of iron ore. All the ex-isting iron and steel plants in the country utilize hemati-tic ores, though a few deposits of magnetite are also being considered for utilization. Until very recently only hand-mining was employed to prepare iron ore of uniform size and composition for smooth blast-furnace operation. The ore ...

Therefore, this work is aimed to experimentally study the iron ore slime beneficiation using a novel 100 mm hydrocyclone (with small cone angle, tapered vortex finder and optimum cylindrical ...

Beneficiation studies of iron-ore fines and slime have been made to ascertain the selectivity of chemical additives with or without stabilizing agents and/or calcium ion for alumina removal.
