Frothers in flotation: A review of performance and function …
Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and Cilliers, 2009, Hadler et al., 2012, Kowalczuk and Drzymala, 2017a, Kowalczuk and Drzymala, 2017). Although frothers improve flotation rate and recovery, a very high frother ...

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth
This will lessen the time that the poorly mineralized particles has to filter out of the froth. Adding air temporarily lessens the froth column "by taking up space in the float cell. Until the pulp level has had a chance to equalize to its pre-set level the froth column will be shallower.

Flotation Collector Dosage – Over/Under Collection of Froth
As the froth becomes loaded it will begin to float properly until the froth load has floated off. Then it will slow down again until the bubbles have had a chance to load themselves once more. The indicators that show that this is happening is an unsteady speed of the cell overflow, the size of the bubbles becoming large and unstable, slowly ...

Beneficiation of oil shale by froth flotation
The optimal flotation performance occurred for a pulp concentration of 50 g/L, a collector dosage of 1000 g/t, a frother dosage of 300 g/t, an agitation speed of 1900 rpm, and an aeration rate of 160 L/h. Froth flotation is a mature method and is widely used, and thus, it can be used to improve the industrial production of oil shale.
