TECHNICAL NOTES 9 FLOTATION - mineraltech

FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be

Recovery vs. mass pull: The link to air recovery ...

Air recovery, or the fraction of air entering a cell that overflows the lip as unburst bubbles, is a robust, non-intrusive measure of froth stability that passes through a peak as cell air rate is increased. Furthermore, it has been shown that when operating a cell at the air rate that yields the ‘Peak Air Recovery’ (PAR), an improvement in ...
