1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

1.. IntroductionFlotation is an important process in the minerals industry and most flotation is carried out using mechanically agitated cells ranging in volume up to 300 m 3.Separation of the particles of valuable minerals from the ore is achieved when particles of the valuable minerals preferentially attach to air bubbles and are floated to the surface of the slurry …
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 of high selectivity.

Flotation cell
The primary difference in flotation cells is the two ways of introducing the gas. Gas introduced into the bottom of a cell and dispersed into a water in the form of very fine bubbles will rise to the top of that cell and carry with it suspended solids and entrained oil. Additional frothing can be created by injecting surfactants or other water ...
