Froth Flotation of Iron Ores
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 be lost in the beneficiation process.
