The significance of froth stability in mineral flotation — A review
Advances in Colloid and Interface Science, 2011 This paper presents a review of the published articles related to froth stability and its importance in mineral flotation. Froth structure and froth stability are known to play a significant role in determining the mineral grade and recovery achieved in ...

, 2008 Froth flotation is a process used to separate minerals, suspended in liquids, by selectively attaching them to gas bubbles. Hence, in flotation we have a three-phase system.

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.

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 ...

The rheology of flotation froths
International Journal of Mineral Processing, 2003A literature review has highlighted the need to measure flotation froth rheology in order to fully characterise the role of the froth in the flotation process. The initial investigation using a coaxial cylinder viscometer for froth rheology measurement led to the development of a new device employing a vane measuring head.

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.

On the kinetics of froth flotation
International Journal of Mineral Processing, 1990Abstract The problem of froth flotation kinetics is treated as a transport phenomenon. Two coupled equations of balance are formulated which concern the particles attached upon the bubbles and the free particles in the pulp. The combined equations are solved and an analytical expression for the recovery as a function of time is obtained.

Mineral Processing and Extractive Metallurgy Review, 1993
Good flotation frothers have branched hydrocarbon radicals and form loosely packed gaseous films at the liquid/gas interface. Their hydrophile-lipophile properties must be properly balanced and for most good frothers the HLB values are close to 6. This allows them to co-operate actively with the adsorbed collector in the moment of particle-to-bubble ...

Modeling of Visual Flotation Froth Data
IFAC Proceedings Volumes, 1998Abstract In this paper, the principles of sensor fusion are presented. A new sparse coding method based on a generalization of the generalized Hebbian algorithm (GGHA) is presented. The algorithm is realized using a modification of the Kohonen network.
