About convection-diffusion dynamic model of apatite flotation process**On a convection-diffusion dynamic model of the apatite flotation process**

Abstract
In the works of a number of researchers it has been shown that a satisfactory mathematical description of once-through flotation machines cannot be obtained without taking into account the effect of longitudinal mixing of the pulp, which is equivalent to turbulent diffusion and leads to an equation of the form.An exact description of convective mixing requires a specific mathematical apparatus. However, its absence makes it possible to raise the question of whether the diffusion equation can be used for these purposes, but on the condition that the diffusion coefficient is selected so that the mixing effect of the equivalent diffusion proves equal to the mixing effect of convection and diffusion acting jointly.
