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.
