Dynamic Froth Stability in Froth Flotation
Minerals Engineering, 2003 A new measure for froth stability is introduced in this work, based on a dynamic stability test for non-overflowing froth columns. The dynamic stability factor represents the lifetime of a bubble in the froth, and is defined as the ratio of the total volume of froth at equilibrium to the volumetric gas rate introduced into the system.

Effect of Flotation Froth Properties on Froth Rheology
Powder Technology, 2016 Froth flotation is a widely used process of particle separation exploiting differences in surface properties. The froth performance in a flotation cell is expected to be affected by the froth rheology, as it affects the froth residence time that ...

The Froth Stability Column: Linking Froth Stability and Flotation Performance
Minerals Engineering, 2005 Froth structure and stability are known to play important roles in determining mineral flotation recovery and selectivity. However, measuring froth stability quantitatively, both at laboratory and industrial scales remains a significant challenge.

Effect of Froth Rheology on Froth and Flotation Performance
Minerals Engineering, 2018 It has been suspected for some time that froth rheology has an impact on froth and flotation performance but little experimental work has been performed to investigate these effects.

Modelling for Froth Flotation Control: A Review
Minerals Engineering, 2021 Flotation is a conceptually simple operation; however, as a multiphase process with inherent instability, it exhibits complex dynamics. One of the most efficient ways to increase flotation performance is by implementing advanced controllers, such as ...

Flotation is a selective separation process by attaching hydrophobic particles to rising air bubbles to form a particle-rich froth on the suspension surface, which flows over the lip of the cell. Hydrophilic particles do not attach to the bubbles and settle to the bottom to be discharged.
