    Iron ores and manganese ores are the main ones for which we use magnetic separation. Magnetite and Chromitite ores (both iron ores) use this method on a large scale to remove their impurities. Learn the process of extracting Crude Metal from Concentrated Ore. Froth Flotation Process. Another method of concentration of ores is the Froth.Therefore, these mines crush and grind the ore, then use gravitational and magnetic concentration methods to produce concentrates with an iron content of about 65 . Depending on grain size, the concentrate is then shipped as is, or agglomerated into balls about a centimetre in diameter and fired to produce hard iron ore pellets.
