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.
