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.

Foam/Froth Flotation

Separation and Purification Methods, 1991
Abstract In this second part of the Review on foam and froth flotation, many other aspects of the flotation process are examined, referring mainly to the separation of particulate matter. The effect of particle size is analyzed, stressing the effect of the finer fractions; the role of bubble size is also examined.

Modelling flotation froths

International Journal of Mineral Processing, 2003
Abstract This paper gives a brief description of a fundamentally based model for the behaviour of a flotation froth. It includes descriptions for all three phases present in a flotation froth. The model for the gas motion uses either the simpler Laplace equation for describing the gas motion, or a more complex model for froths in very complex ...

Froth Flotation

2013
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.
