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.

SF Flotation Cell/Machine Working Principle When the rotor is rotating, an internal vacuum is created both in the upper and lower blade zone. Ambient air is drawn through an air intake pipe and standpipe by the action of the upper blade, the bubbles are then micronized and make the minerals easier to stick on the bubbles.

Cytec Handbook. Capacity. Floating time of the ore is one of the determining factors in figuring the capacity. If an ore is slow floating and requires twelve minutes treatment time, and another ore is fast floating and requires but six minutes treatment, it is evident that a machine of only half the capacity is necessary in the last instance.
