Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used. The upgraded ore, or concentrate, is in the form of a very fine powder that is physically unsuitable for blast furnace use.
