FIELD: mining industry.
SUBSTANCE: invention can be used in the development of natural and man-made high-clay alluvial mineral deposits with a high content of fine gold. In the method of cavitation-hydrodynamic microdisintegration of the polymineral component of the slurry, a high-speed jet from the diffuser is supplied to the upper inclined surface, made with an offset relative to the axis - above the level of the underlying inclined surface – (of) a conical edge and cavitation inclined sills installed along the entire inclined surface across the flow of the slurry for the layering and amplification of oscillations. To enhance the cavitation-acoustic effect on the polymineral component of the slurry and obtain a given average value of the bulk density of the hydrodynamic disturbance to provide a pressure gradient with exceeding the tensile strength of microparticles, the slurry flow cascades onto sequentially and stepwise installed inclined surfaces in the middle part of the body and the lower confuser along the direction of the slurry flow, with alternating of inclined surfaces with a conical edge on one side, and on the other side - inclined surfaces with a straight edge, also equipped with cavitation inclined sills installed along the entire inclined surface across the flow of the slurry to stratify the flow of the slurry and enhance oscillations, and support radius elements and rods to increase the rigidity of the structure. The gaps between the lower surfaces of the tapered edges under the corner points and the levels of the underlying inclined surfaces vary depending on the ratio of solid to liquid in the slurry.
EFFECT: increase in technological and operational efficiency of the process of deep disintegration of the polymineral component of the slurry.
