Predicting flotation behaviour – The interaction between ...

2018-5-1  Froth behaviour has a major impact on the overall performance of flotation cells, with the froth controlling the water recovery and entrainment, as well as having a significant impact on the recovery. Froth stability, including bubble coalescence and the bursting of the bubbles at the froth surface, are the key drivers of froth performance.

All You Need to Know About Mineral Processing -

Mineral processing is the art and technology of treating ores from the mining areas in order to separate the valuable minerals from the waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The two main processes to increase the concentration of minerals are leaching and flotation.

Effect of froth rheology on froth and flotation ...

2018-1-1  Hence, froth recovery is likely to be positively correlated with air recovery. It is expected that froth rheology can influence froth and flotation performance through its effect on froth retention time. A more viscous froth resists motion towards the lip, increasing the time the froth remains in the flotation cell.
