Column Flotation Cells - Mineral Processing and Metallurgy

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 - an overview ScienceDirect Topics

Column cells have been developed over the past 30 years as an alternative to mechanically agitated flotation cells. The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs.

What Are Column Flotation Cells? - Industrial Resources

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation impellers .

Column and Contact Cell Flotation Mining SGS

Column Flotation. Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic water-repellent by conditioning with selective flotation reagents.

Column Flotation Theory and Practice

Column flotation which employs a counter-current flow of slurry and air bubbles has proved to be a better alternative to the conventional mechanical cells for separation of minerals. Because of the distinct advantages of column flotation over mechanical cells, it is gaining wider acceptance in industry.
