Froth Flotation of Iron Ores - Scientific & Academic PublishingJan 2, 2012 . The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina/hematite separation than for quartz/hematite separation. Das et al.[28] studied the beneficiation of some alumina-rich iron ores and reported that to reduce alumina content by 4%, as much as 45% Fe has to.flotation iron ore beneficiation magnetite,Reagents types in flotation of iron oxide minerals: A review: Mineral .Nov 2, 2017 . Recently, beneficiation of iron from low-grade ores with high impurities has been a matter of discussion. Flotation is one of the most effective technologies for the upgrading of low-grade, finely grained iron ores. This method can also be applied to reduce the impurities content in magnetite concentrates.
