Column Flotation Cells. Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable …

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 Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
