Column Flotation Cells - Mineral Processing Metallurgy

2016-2-28  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.

Laboratory baffled-column flotation of mixed Lower/Middle ...

The separating efficiency of a flotation column is largely limited by the degree of back mixing of tailings into the froth zone, and the recovery is limited by the degree of short-circuiting of feed to the tailings. Current columns are typically constructed very tall (30 to 40 ft) to limit the effects of back mixing and short-circuiting. These effects can also be reduced in a much shorter ...

COLUMN FLOTATION MODELLING AND TECHNOLOGY

2010-9-23  Industrial flotation columns are square or circular, typically 0.5-3m in diameter or side, and 12-15m height. Since their invention, square columns have been marketed commercially by the Column Flotation Company of Canada Ltd. The apparent simplicity of the column has led others to copy the original idea and make their own "homemade" columns.
