Abstract
In terms of galena, the authors specify construction principles for kinetic “ion” modeling of surface layer composition on grains of sulfide minerals of nonferrous heavy metals during flotation. The physical sense of the models consists in connection of parameters of ions within liquid phase of flotation slurry with relative fractions of mineral grain surface. Commercial tests proved the theoretical concept on formation of sorptive layer of sulfhydryl collectors on the surface of sulfide mineral grains under flotation conditions.
