The new-developed approach to analyzing two-phase flow in mineral separation and beneficiation is based on the physical analogy of the flows and the perfect gas kinetic theory. The analysis from these viewpoints allowed formulation and basis of the invariants of such flows, where the key invariant is entropy of the two-phase flow, and its derivatives are potential extraction, chaotization factor and flowability. The mathematical modeling of the two-phase flow from the new points of view permits analyzing the flow using statistical mechanics techniques.
