FIELD: mining.
SUBSTANCE: invention relates to the mining industry and can be used in the development of natural and man-made high-clay alluvial deposits of minerals with high content of fine and fine gold, as well as during processing of ash-slag wastes containing native gold, platinum and silver. Method for activation of cavitation-hydrodynamic microdisintegration of mineral component of hydraulic mixture includes high-speed supply of jet into hydrodynamic generator, treatment of hydraulic mixture in conditions of active hydrodynamic actions by means of effect of stationary elements arranged inside the housing and installed in series with provision of deep disintegration of mineral component of hydraulic mixture to micro level, including – by conversion of kinetic energy of liquid flow to energy of acoustic oscillations in hydrodynamic generator, in which, in order to create conditions of system stability, taking into account electrostatic interaction of diffuse layers of ions of particles of mineral component of hydraulic mixture, high-speed jet is supplied to crosspiece with multi-row cartridges fixed rigidly along hydrodynamic generator axis. In order to intensify primary hydrodynamic fields and to create secondary acoustic cavitation, cascade flow of hydraulic mixture is performed to serially installed in central part of hydrodynamic generator in direction of hydraulic mix movement, multi-row cassettes with variable volume of rows both vertically and horizontally and fixed on walls of inner compartment of hydrodynamic generator and crosspieces. For cavitation activation in zones formed between walls of inner compartment of hydrodynamic generator and external walls of hydrodynamic generator, forming zones of narrowing to cylindrical central part, cavitation effects are created by means of cone-shaped surfaces truncated horizontally and vertically, which are truncated in upper zones of narrowing, with positioning of large bases at top.
EFFECT: high complexity of extracting minerals, low power consumption, improved operational performance of servicing hydro-generator, high profitability of production and low environmental load.
