Scientific pre-requirements for development of promising dry and low-water-consumption technologies for finely ground mineral materials processing have been considered. Such technologies and equipment for their realization may be based on application of vibratory effects, in particular, on the effect of separated material vibrational fluidization. In vibrational fluidization state, particles move relative to one another with partial loss of contact. With that, particles detach from one another with thorough mixing. Dry separation of powder-particles smaller than 0.5 mm by their mechanical-and-physical properties is possible in the following processing operations: size classification; separation of particles according to magnetic properties; separation of particles according to electrical properties. In addition to that, subjecting of flotation slurry to vibrational effects opens the way to development of vibratory flotation machines, operating with slurries of significantly higher density, than slurries in conventional mechanical-air and pneumatic flotation machines. This in its turn creates prerequisites for drastic cuts in process water consumption in flotation – the most mass-scale process used for non-ferrous metal ores benefication.

The work was performed with the aid of the Grant 14.579.21.0023 from the Ministry of Education and Science of the Russian Federation, UIPNI RFMEF157914X0023.
