Selective Aggregation of Hydrophilic Gangue Minerals in Froth Flotation

In a highly dispersed flotation pulp, ultrafine hydrophilic minerals can entrain into froth products even though they may be perfectly hydrophilic. Therefore, effective depression of the hydrophilic minerals in froth flotation relies not only on rendering the minerals hydrophilic, but also on proper particle size control. In this paper, it will be shown that several depressants in …

Phenomena in the froth phase of flotation — A review

Froth flotation was commercially introduced early in the 20th century. Now, almost 100 years later, it is the most important and widely used separating method for minerals.In its application to mineral flotation, the ore is first ground in water to a certain size to produce a suspension which is then subjected to vigorous mixing in a suitable vessel.
