Role of frother on bubble production and behaviour in ...

1. Introduction. The addition of frother is nearly universal in mineral flotation plants. Among the exceptions are operations where high salt levels in the process water can replace the two prime functions of the frother, namely to act in concert with the gas dispersion device to control (reduce) bubble size, and to provide froth-building capacity.

Typical Families of Flotation Frothers – Frothing Agents The dosage of frother required in any given application is quite variable, ranging from zero in some systems to 0.3 kg/ton in others. Part of the reason for this variability is that many collectors presented earlier demonstrate some frothing action as well as collecting action.
