Experimental observations of bubble–particle collisional interaction
This paper modifies an experimental system previously used by Verrelli et al. to investigate particle–bubble attachment. Three different flow configuration cases were studied to investigate the effects of flow environment on the particle–bubble interactions and to model a situation more characteristic of real industrial froth flotation processes.

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 ...
