Power is related to cell volume. For small cells it can be up to 2.11 kw/m3 to as low as 0.6 kW/m3 for very large cells. Power is a major cost for flotation and power is reduced with larger flotation cells. The internal pumping within a cell increases gas dispersion and therefore enhances bubble particle contact and hence flotation.
