Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
Clearly there is an enormous range in bubble resonance frequency for bubbles in the 100–1500 μm radius range, being inversely proportional to bubble radius. Fig. 1 indicates a range of ∼2–42 kHz for bubble radius decreasing from 1500 to 100 μm, which should cover the size range of bubbles likely to be generated in normal operation …

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. …
