The analysis of the main regularities of distribution of the material in stages of the vertical cascade makes it possible to substantiate the optimality of some important parameters of separation. It is shown that the best efficiency of separation can be attained as a result of feeding of the source material into the central part of the cascade. In this case, the number of stages should be restricted because the efficiency of separation decreases as the number of stages increases. The proposed analysis also reveals some shortcomings of the generally accepted velocity-based hypothesis in the theory of gravitational processes, which occupies a central place in the analyzed theory until now.
