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. Slurry mineral component cavitation-hydrodynamic micro-disintegration activating method includes the jet high-speed supply to the diffuser of the hydrodynamic generator, slurry treatment under conditions of active hydrodynamic influences by means of influence placed inside the cylindrical body with a confuser and subsequently installed stationary cavitation elements, including plate cavitation elements, thin-jet separation with the provision of the slurry mineral component deep disintegration to the microlevel by converting of the liquid flow kinetic energy into the acoustic oscillations energy in the hydrodynamic generator. To strengthen the primary hydrodynamic disintegration fields at the diffuser exit, creating the turbulence and dilated sparseness through removable cartridges with grids, which overlapping are made at an angle in the horizontal plane in relation to the cylindrical body horizontal axes, from the angle beams, which right angle is turned upwards. Each of the angle beams subsequent layers is installed with the opposite slope in relation to the previous layer, and the distance between the angle beams along the horizontal line varies from the previous layer to the subsequent layer along the vertical line in accordance with the predicted reduction in the slurry solid component elements maximum size. Vertical distance between the angle beams previous layer and the subsequent layer exceeds the angle beams height depending on the strength, elastic-geological and thermo-physical characteristics of the slurry solid component, and also of the slurry S:L ratio. Subsequent fine-jet separation with cavitation is accomplished by means of plate cavitation elements, installed in the hydrodynamic generator cylindrical body lower part under the removable cartridges with grids with the stepwise change of the surfaces upper horizontal lines with a reduction to the cylindrical body central axis, and the surfaces lower lines is with the provision of an additional turbulent mode through a one-sided oblique cut and the slurry free entrance into the confuser.
EFFECT: increasing the micro-disintegration process efficiency.
