FIELD: mining industry.
SUBSTANCE: proposed invention can be used in development of natural and technogenic high-clay alluvial deposits of minerals and ore-placer units. Method for microdisintegration and activation of the polymineral component of the slurry includes the supply of the processed material into the oversize compartments of parallel semicircular sections of the hydrodynamic disintegrator screen simultaneously, gripping of processed material by edges of spiral elements installed on rotors with inclination in vertical plane along horizontal axis in accordance with inclination of bottom of oversize compartments, for movement in inter-labyrinth space to opposite edge for further processing. Processed material is fed into semicircular sections after removal of boulders by means of high-speed supply of slurry jet by pump through nozzle to flat surface of splitter, conjugated with a cone-shaped divider between semicircular sections along the flow of the slurry, to form zones, promoting activation of microdisintegration by alternating spiral elements, and physical and mechanical action on the mineral component by spiral cutters for the power abrasive action on the gold with quartz and pyrite intergrowths in the microbonds destruction activation sections, enhancing activation of microdisintegration in sections of microdisintegration and separation in sections of separation of clay component from polymineral component, arranged in series and arranged below the level of the bottom of the oversize compartment with a threshold for draining the clay component, installed with a gap, and a sieve made behind the threshold for draining the clay component in the direction of movement of the slurry. Spiral elements intended for disintegration are equipped with discs with ribs, bushings for fixation of disc in inter-labyrinth space, nuts for attachment to rotor shaft from outside. Discs with housing are made with bevel for gripping of processed material and movement in inter-labyrinth space. Ribs are made on both sides of discs for turbulence.
EFFECT: high technological and operational efficiency of the microdisintegration process, activation of the destruction of bonds in intergrowths and separation of the polymineral component of the slurry.
