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.
