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.

Flotation optimization. Lost recovery in the flotation process results in lost revenue. Mines now need to process more complex ores making the operation of flotation circuits more difficult. Our service helps identify the optimum feed size, cell design and operational parameters to maximize recovery and revenue.

TECHNICAL NOTES 9 FLOTATION - Mineral Tech

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified.
