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.

The flotation machine is used for mineral processing. The ore slurry is doped, stirred, aerated, and mineralized through a preprocessor so that some of the mineral particles are selectively fixed on the bubbles; they float to the surface of the slurry and are scraped out to form products. It is retained in the slurry to separate minerals.

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.
