Iron ore slimes flotation
The ores having ferro-magnetic minerals are suitable for magnetic separation methods. Some of the studies investigated flotation [7], and reflux classifiers [8] for beneficiating the iron ore fines or slimes. None of these methods are capable of treating all size ranges and types of iron ore satisfactorily.
