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.

Lab #5 – Froth Flotation
all sulfide minerals are treated by froth flotation, as well as many oxide minerals and industrial minerals. In this process, mineral particles that have an affinity for air, known as hydrophobic particles, selectively attach to air bubbles and are recovered in the froth at the surface of the flotation machine.
A significant review of froth stability in mineral flotation
Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, whereas hydrophilic …
A review of froth flotation control
The two higher tiers of flotation control are advanced flotation control (AFC) and optimising flotation control (OFC). AFC involves the rejection of the effects from input disturbances to the process (e.g. a change in feed grade) and maintaining performance parameters — grade and recovery (although care should be taken when defining recovery; in …
