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 productive solution and its hydrometallurgical processing and 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 of tailing dumps. According to the disclosed method, the supply of the aqueous product solution is automatically proportional to the drop of the pool mirror level by the flow of the laminar flow to the interface of the water fraction and the fraction of the collective concentrate, removal of water from the pool is carried out automatically by impregnation with water of absorbing peat belt cartridge by drawing it under the pool mirror with subsequent extraction of active components of peat by means of heating and treatment with ultrasound and sloughing of peat water, which is returned to the underground leaching process, and the collective concentrate is discharged automatically self-regulating the drain when the specified maximum and minimum levels of the collective concentrate in the pool liquid volume are reached. Method is carried out using self-adjusting system containing outdoor pool on day surface of the earth, filled with aqueous solution, an aqueous product solution supply pipeline, equipped with a shut-off valve and a pipeline for dispensing a collective concentrate of useful ore components, equipped with shutoff valves, characterized in that the pipeline of water-producing solution supply is equipped with shutoff-control valves, servo drive, basin mirror level sensor and is connected by flexible hose with laminar equilibrium flow platform. Pipeline of collective concentrate is equipped with shutoff and control valves, servo-line, end switches of upper maximum level and limit switches of lower minimum level. System includes a peat belt cartridge, a tape mechanism, an extractor bath, a roller peat sloughing device, an extraction efficiency sensor and a peat sloughing tank.
EFFECT: efficient enrichment of an aqueous product solution in continental climatic conditions of a demi-season period, as well as providing recycling of process water.
