Froth Flotation Improvement

Jul 01, 2021 The improvement in flotation performance presented in the present work might not be solely due to the increased froth stability. A recent theoretical study found that presence of acoustic sound could affect bubble-particle interaction (Yasmin et al., 2019). It was claimed that the sound could induce bubble oscillation and the oscillatory motion could increase the effective bubble surface area

Adding increased air rate in flotation should increase the recovery. Floating (collecting froth) for a longer time should increase the recovery. If the froth looks very weak (bubbles breaking easily) then you may want to add one or two more drops of frother to help make the froth stable
