Phenomena in the froth phase of flotation — A review
Abstract. The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
