FIELD: mining engineering.
SUBSTANCE: method includes velocity delivery of a jet to a hydrodynamic generator, treatment of the hydraulic mixture under the conditions of the active hydrodynamic effects by means of the influence of a body placed therein and successively installed stationary elements providing deep disintegration of the mineral component of the hydraulic mixture to the micro-level by converting the kinetic energy of fluid flow into the energy of acoustic vibrations in the hydrodynamic generator, which at inlet a high-speed jet is created. The high-speed jet is fed to stationary elements including a splitter with helical blades which are engageable with the upper inclined surface with an elliptical hole displaced in one of the sides and cavitation inclined thresholds installed at its bottom part by an acute angle towards the flow of the hydro-mixture for separation of the flow and amplification of the oscillations. In order to amplify the fields of the primary hydrodynamic cavitation and to create the secondary acoustic cavitation, there is a cascade overflow of the hydraulic mixture into successively and stepwise inclined surfaces arranged in the direction of movement of the hydraulic mixture with displaced elliptical openings at different sides, relative to previous and subsequent inclined surfaces, with cavitation inclined thresholds installed on the lower parts of the inclined surfaces by an acute angle towards the flow of the hydro-mixture for intensification of the cavitation-acoustic effect on the mineral component of the hydraulic mixture.
EFFECT: increased efficiency of deep disintegration process of hydraulic mixture mineral component of placer clay sands.
