1 Froth Flotation – Fundamental Principles
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
Flotation Column Cell Carrying Capacity & Scale-Up

Basic Principles & Variables Affecting Froth Flotation
A certain degree of stability is essential in every froth, enough to allow for the removal of the froth from the flotation machine. Stability of froth is affected by the extent to which the bubble walls are covered by solid matter and by the strength of the liquid films of the bubbles themselves. The more closely particles of solid are packed ...
