  • Role of frother on bubble production and behaviour in

    1 IntroductionThe 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.

    For example, if 20% of the water entering a flotation cell is carried into the froth, then up to 20% of the fine particles entering the cell will be entrained. The entrainment of coarser particles will be less than 20%, due to their greater ability to drain from the froth.
