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).
2018 8 22ensp;0183;ensp;Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as

Isotopic separation is fairly easy in light elements since low masses mean relatively large mass ratios (Li 7 is only one atomic mass unit heavier than Li 6, but it is 17% heavier; U 238
