Flotation, on the other hand, is used to reduce the content of impurities in lowgrade iron ores [12,5]. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used in the iron industry [5,7].
