Abstract
The article describes the method of potentiometry in determination of characteristic diameters of air bubbles. The authors discuss feasibility of the Sauer diameter measurement of air bubbles using the difference of electrode potentials at different depths in flotation machine and with further evaluation of aeration intensity. The studies involved a two-phase system at different consumptions of air and frother. The highest aeration intensity is found from the checking tests of a three-phase system. It is found that the rate of increase in the difference between the electrode potentials linearly correlates with the Sauter diameter of air bubbles.
