    Froth Flotation of Iron Ores

     · The reverse cationic flotation route widely used in the ore industry is less selective for alumina/ separation than for quartz/ separation. Das et al.[28] studied the beneficiation of some alumina-rich ores and reported that to reduce alumina content by 4%, as much as 45% Fe has to be lost in the beneficiation .
