Improving flotation energy efficiency by optimizing cell hydrodynamics
The installed power per cell (i.e. power draw) increases almost linearly with increase in cell volume (Fig. 1).On the other hand, the specific power (kW/m 3) decreases dramatically as cell volume increases from 0.02 m 3 to about 20 m 3 reaching a minimum of around 1 kW/m 3 for cell volumes greater than 100 m 3..

Jameson Cell
Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.
The future of flotation
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. ... To float the same amount of material, the SFR requires less power and a smaller plant footprint than a conventional flotation cell. Courtesy ...
