CHATFeb 28, 2016· 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 tests were carried out in a 1.5 L lab flotation cell, at 150 g solids/L pulp density. Both flocculants were found to strongly depress coal flotation the higher the flocculant dosage, the smaller the yield of the concentrate, higher its ash content, and lower ash content in the flotation tailings.

Design of plant circuits from laboratory data usually relies upon a flotation columns should be considerably more fruitful, for the following reasons 1. There is no mechanical agitation; 2. Close control is maintained over pulp rates and air rate; characteristics change from cell to cell. Industrial flotation columns are square or

Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet (7.6m) to more than 50 feet (15.2m). The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.
