FIELD: mining.
SUBSTANCE: proposed group of inventions relates to mining, to geotechnological methods of extraction of solid minerals, in particular by underground leaching (UL) with subsequent enrichment of produced aqueous solution and its hydrometallurgical processing, can be used in development of: deposits in heavily flooded and unstable sedimentary rocks, ores of oxidation zones of sulphide deposits, off-balance areas, deep-lying deposits with poor ore, dumps and tailing dumps. In the method of enriching the aqueous product solution during the winter season, supplying the aqueous product solution automatically in proportion to the pool table level drop, removal of water from the pool is performed automatically by accelerated freezing of ice in the form of cylinders and their periodic extraction from the near-surface water layer of the pool with subsequent return of water after enrichment in the process of underground leaching by impregnating swamp peat deposits, overlapping the extraction section of the ore deposit during spring melting of ice. Collective concentrate output is performed automatically at achievement of specified level of collective concentrate in volume of pool fluid. Method is carried out using an actuator comprising an outdoor pool on a day surface of the earth, filled with an aqueous solution, an aqueous production solution supply pipeline equipped with shutoff valves, ice fixator, device for extraction of ice from water surface of pool, pipeline for distribution of collective concentrate of useful components of ore for storage, equipped with shutoff valves. Actuator also comprises a wind trap, a cooling slope of the shallow side of the basin, a water flowing cylindrical core of ice roll, mechanism for rotation of ice roll and its extraction from near-surface water layer, sensor of immersion of ice roll, ice break wall, pipe for supply of water productive solution is equipped with shutoff and control valves, servo drive, basin mirror level sensor, collective concentrate delivery pipeline is equipped with shutoff-control valves, servo drive and collective concentrate level pickup.
EFFECT: technical result is providing effective enrichment of aqueous product solution in continental climatic conditions of Siberian winter, as well as recycling commercial water in process of underground leaching.
