Froth Flotation of Iron Ores

Jan 02, 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. 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.

CHAPTER 9 FROTH FLOTATION AND ITS APPLICATION TO

Flotation of iron ores can be done in two ways, 'direct' or 'reverse'. In the former, iron oxide is floated. Anionic reagents, such as petroleum sulfonates or fatty acids, are most commonly used. Structurally, these reagents have negatively charged ionic `heads' attached to long chain organic 'tails'.
