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.

The use of machine vision to predict flotation performance

The superficial gas velocity is related to the froth transport factors in the flotation cell. Gorain (2005) showed that in lead and zinc flotation circuits the superficial gas velocity within a cell followed a linear relationship with the froth velocity. However, it was acknowledged that this relationship changed under different feed conditions.
