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.

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 ...

Foams and froths are of considerable practical importance not only in froth flotation of minerals or in adsorptive bubble-separation techniques applied to water purification but also in the food industry. Protein-stabilized foams have to be carefully controlled in the boiling and the fermentation stages of food preparation.

To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed. Provided these produce sufficiently marked differences of behaviour in the presence of air, they can then be exploited.
