Abstract
Mathematical model of flotation in dispersed mixture of liquid, solid, and gas phases has been designed within the considerations of the mechanics of multiphase media with the assumption of the degree of mineralization of the bubble surface. The application of the designed model has been demonstrated based on the example of one-dimensional stationary flotation and it has been shown that the equations that describe the emergence of bubbles are singularly disturbed (“rigid”). The effect of size and concentration of bubbles, as well as volume content of dispersed particles, on flotation has been analyzed.
