The flotation chemistry is the same for both flash flotation and standard flotation, but the hydrodynamics and froth phase are quite different (Jameson, 1984, Yoon, 2000, Tsatouhas et al., 2006, Arellano-Piña et al., 2017). Although, in a flash cell, it is commonly accepted that coarse particles float, it should be considered that, by removing ...

Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing.
