Column Flotation Cells - Mineral Processing & 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 columns: Getting the most from fine ores - Outotec

Flotation columns: Getting the most from fine ores; Flotation columns: Getting the most from fine ores. The first flotation machine design to use the column concept was developed by Town and Flynn in 1919 – a column was used with an injection of air in the bottom by a porous plate.

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). Mixing is achieved by the turbulence provided by the rising bubbles.
