Bubble-particle interaction in flotation cell
(University of Science and Technology Beijing, Beijing 100083, P. R. China)
Abstract: Three elementary processes of bubble particle interaction: collision, adhesion and detachment, in turbulent flow of flotation cell were analyzed. A general equation describing the particle bubble interaction was derived, which allows us to evaluate the flotation rate constant quantitatively. The results of calculation were verified experimentally.
