Introduction: The flotation machine is important for realizing the flotation process. It can process metal or non-metal minerals, such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration.

Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The …

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 zone controls the degree of the capacity of flotation columns because the capacity of the flotation column depends on the intensity of bubble-particle collision, the probability of attachment and surface area of the gas bubble. Cleaning zone: the zone above feed slurry to froth interface level. Froth zone: the zone above the interface.
