TECHNICAL NOTES 9 FLOTATION
Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.

Flotation behaviour in reflux flotation cell – A critical review
The change of flotation feed size leads to new challenges in designing flotation equipment and circuits. For conventional flotation circuits, a typical feed size is in the range of 75–150 μm (Jameson, 2010b).As described in the famous 'elephant curves', for most of the base metal sulphide minerals, this size range provides the highest recovery in conventional flotation …
