Gases affect bubble sizes - Froth Flotation (Sulphide ...

Frother is a reagent that avoids coalescence, in other words it preserves the bubble size produced by the gas dispersion mechanism. If your system does not have frothed or if it is lower than the CCC you will not be able to take advantage of the minimum bubble size produced by any given flotation technology.
