In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. …

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 ...
