Mineralogical and Beneficiation Studies of a Low Grade Iron Ore
Magnetic separation is an important beneficiation process and is usually adopted for ores of manganese, phosphate, titanium, chrome, tungsten, molybdenum, nickel, bauxite and niobium-tantalum ores in addition to iron ores [1–13]. Magnetic separation methods were also carried out for the ferrochrome industry wastes such as A pyrolusite concentrate with a manganese oxide con-tent of 20 % was obtained by means of a jigging ma-chine, with subsequent high-intensity magnetic separa-tion it was possible to increase the MnO content to 44,3 % with an extraction of 61,3 %.
