The regime of two-phase ascending flow in which the solid phase can move in both directions is called critical. The analysis of such flow from the standpoint of statistical approach made it possible to establish key parameters characterizing such mass transfer process. The chaotizing factor and solid phase mobility are among the energy characteristics of this process. It was shown that two-phase systems, which can exchange energy and particles, evolve towards an equilibrium state with maximal entropy. In this case, the ratio between mobility factors and chaotizing factor in all parts of the system acquires the same value. The analysis of this ratio leads to a universal affinization criterion of separation curves. In this respect, the identity of this criterion for different size grades ensures their equal extractability. A correlation between the key parameters characterizing a two-phase flow as a statistical process has been determined.
