FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used during development of the natural and anthropogenic high-clayey gravel deposits of minerals with high content of fine and thin gold. Method of activation of micro-disintegration of high-clay polymineral component of hydraulic mixture includes high-speed supply of jet, treatment of hydraulic mixture in conditions of active hydrodynamic actions by means of influence of profiled narrowing and expanding channels forming housing of hydrodynamic generator, as well as in-series installed stationary cavitation elements in the form of beams-angles, separation with provision of deep disintegration of polymineral component of hydraulic mixture to micro level by conversion of kinetic energy of liquid flow into energy of acoustic oscillations. To amplify fields of acoustic oscillations at the outlet of the upper diffuser, turbulence is created, which changes into rarefaction by means of confusor rigidly fixed along the wall along the entire height – to the lower spider – elongated beams-angles, the edges of the right angle of which are turned upwards towards the flow, and forming a cavitation zone in confuser lower part. In segments – between elongated beams-angles – with opposite inclination in vertical relative to elongated beams-angles there are short beams-angles, edges of right angle of which are turned upwards towards the flow. Upper ends of short beams-corners are rigidly fixed on upper crosspiece, and lower ends – on middle crosspiece of confusor. Subsequent turbulent mode is carried out by means of stiffening ribs installed with inclination in lower part of housing – lower diffuser of hydrodynamic generator. Shaped converging and diverging channels of hydrodynamic generator housing are composite.
EFFECT: increasing the micro-disintegration process efficiency.
