the flotation-filter unit. As the same velocities prevail in a conventional flotation unit and in a filter (5-12 m · h –1), the idea was conceived to use the lower part of the flotation unit as the top of a filter (figure 34): instead of the traditional cell floor, a filtering medium would be laid over a floor equipped with nozzles; a regulation mechanism would be fitted to the filter water ...

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited.

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.
