FIELD: mining.
SUBSTANCE: disclosed group of inventions relates to mining, to geotechnological methods of extracting solid minerals, in particular, by the method of underground leaching (UL) with subsequent enrichment of the obtained aqueous product solution and its hydrometallurgical processing, can be used in mastering: 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. According to the method of enriching the aqueous product solution during the winter season, supply of the aqueous product solution is performed automatically in proportion to the drop of the pool mirror level, removal of water from the pool is carried out automatically by accelerated freezing of the ice sheet on the shallow-water side of the basin by directed atmospheric air blowing and its continuous extraction from near-surface water layer of pool by means of gripping-broaching mechanism of ice sheet with sensor of control of thickness of frozen ice sheet, collective concentrate is dispensed automatically at achievement of specified level of collective concentrate in volume of pool fluid. Method is carried out using an automatic device 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, and a pipeline for dispensing a collective concentrate of useful ore components for storage, equipped with shutoff valves, a device for extracting ice from the water surface of the pool. Device additionally comprises a wind trap, a cooling slope of the shallow side of the basin, a grip-draw mechanism of the ice plate with a thickness sensor, a roller conveyor and a guillotine. Pipeline for supply of water-producing solution is equipped with shutoff-control valves, servo drive, basin mirror level sensor. Pipeline of collective concentrate is equipped with shutoff and control valves, servo drive and collective concentrate level gauge.
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.
