Phenomena in the froth phase of flotation — A review

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.

Entrainment in froth flotation: The degree of entrainment …

In froth flotation, the degree of entrainment affects the concentrate grade and it is often assumed to be only a function of particle size in models. Literature suggests that other variables might also have a significant impact on the degree of entrainment. ... was derived from the definition of gangue recovery (based on the mass of the gangue ...

Froth Flotation: Factors affecting, Advantages, Disadvantage

Principle of froth flotation. The differences in physicochemical surface qualities of distinct minerals are used in froth flotation. Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment, and for flotation to occur, an air bubble must be able to attach itself to a particle and raise it to the surface.

Froth Crowder

The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.
