Froth Flotation - SMART DOG MINING

This is accomplished by cutting off or decreasing the size of air inlet on the standpipe. Suppressed flotation finds its chief use in certain nonmetallics and occasionally in cleaner or recleaner operations. The aeration and mixing of the pulp with reagents all takes place in the lower zone of the cell. Thorough mixing is to a considerable degree responsible for the metallurgical efficiency of ...

How Froth Flotation Works - Mine Engineer.Com

Flotation machine types vary widely also, but are all very similar, in that they introduce air underwater, and disperse it into the cell. Some use blowers, air compressors, or the action of the flotation impeller creating a void beneath it and drawing air into the machine, via the standpipe which also houses the impeller shaft. It is in the ...

In the flotation cell 12 illustrated in FIG. 1, air is entrained into the fluid by the establishment of a vortex of fluid in the standpipe 54 caused by the turning motion of the impeller 46. Air from the top of the tank 14 (i.e., air existing above the fluid line in the tank) is entrained into the vortex and, additionally, air may be introduced into the standpipe 54 by a pipe or tube (not shown).
