· Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which and other minerals by collecting them on the surface of a layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals .

an overflowing froth (the concentrate). Modern flotation tanks have a volume of 100m 3 to 300m 3, and plants have 3 or 4 flotation stages, each with 6 to 10 tanks. Although occupying less than 10% of the flotation cell volume, the froth behaviour largely determines the fractional and relative recoveries of .
Keywords: Flotation; Bubble load; Froth recovery; Collection recovery 1. Introduction of minerals within the froth phase was usually assumed (Mathe et al., 2000). According to Flint (1974), the single Flotation process modelling kinetic model represents the apparent cell performance where the net result of all processes occurring within a ...

Froth flotation has been a stalwart in mineral beneficiation for more than 100 years. During this time, and particularly in the past 2030 years, there have been significant advances in the design and appliion of mechanical elements for flotation systems,, new mechanisms, launders, larger cell volumes, better pumps, etc.
Froth is an integral part of the flotation system but despite the importance, relatively few studies have been conducted to examine the impact of froth variables ( bubble size, frother type and concentration, liquid/gas/solid content) on the performance of flotation cells 21].
