· Beneficiation of Iron Ores Iron ore is a mineral which is used after extraction and processing for the production of iron and steel The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron magnetite) Ores are normally associated with unwanted gangue material Grade of iron ore is usually determined by the total Fe content in the ore Run of mines ores· Iron ore beneficiation is a multistage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it The iron content of the ore needs to be increased and gangue, which is native rock andWhat Is Iron Ore Beneficiation?
