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.,iron ore and pellets - vale,iron ore is found in nature in the form of rocks, mixed with other elements. by means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. the iron ore produced by vale can be found in houses, cars and household appliances.
