Аннотация: By method of mathematical design and processing of the experimental results, regression equations have been obtained that describe the degree and direction of the effect on the selectivity of zinc recovery produced by the conditions of sorption dissolution, like hydrodynamics of the process, degree of regeneration anal moisture content of the sorbent, and the factors determining the pH of the liquid phase. From the model obtained the optimum conditions of selective sorption leaching of zinc(II) have been determined. The effect of microadditives of redox reagents on the rate of acidic and sorption dissolution. of copper(II) oxide has been investigated at pH = 2-6.
