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 is a separation mechanism engaging numerous interconnected sub-pro- ... the flotation cell (flow rate, amount of material, distribution of particles size, grade, etc.), ... often undergo additional cleaning flotation in subsequent cells to ensure comprehensive recovery of valuable minerals.
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.
