A mathematical model of separating cascade is developed using chain fractions. For its solution, a system of 2z coupled equations (z being the number of stages in the cascade) was examined. On the basis of their solution, final expressions for fractional extraction in the cascade are derived. The analysis of these expressions has revealed the best stage for material feed into the apparatus. A stationary model of the process is developed and discretely solved. This solution allowed us to obtain an instant distribution of the material mass over the cascade stages. Optimization conditions for principal parameters of multistage separation are analyzed. Their empirical adequacy to the obtained results is shown.
