Column Flotation - an overview | ScienceDirect Topics

Modern flotation columns were developed in Canada in the early 1960s (Boutin and Wheeler, 1967) and were first used for cleaning molybdenum concentrates.Two column flotation units were installed in the molybdenum circuit at Mines Gaspé, Canada, in 1980, and excellent results were reported (Cienski and Coffin, 1981).The units replaced the multistage cleaner banks of mechanical cells.

Jameson cell - Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for ...

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.
