(PDF) The significance of flotation froth appearance for machine …
Viscosity, froth volume and mobility of froth According to Moudgil (1993) the frothing properties that are relevant in a flotation process are froth volume, froth viscosity and froth stability. It is desirable that the froth collapses soon after it is skimmed off the flotation cells, since excessive froth volumes cause a loss in throughput.
