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.

Design of Flotation Cells and Circuits

Until only a few years ago mechanical flotation machine capacity was limited to eight to 15 tons of ore per running foot per 24 hours, and this meant that a "small" 10,000 TPD mill needed in the neighborhood of 150 rougher cells, while a 30,000-ton mill would need about 500 rougher cells. With the same units the mill of tomorrow would …
