| description | FIELD: mining art; hydro-metallurgical processing of ores and concentrates; extraction of beneficial components by underground leaching, heap leaching, vessel leaching and tank leaching. ^ SUBSTANCE: proposed method includes preparation of material for leaching-out process, delivery of leaching solution, discharge, collection and reworking of productive solution; intensification of leaching-out process is performed through ultrasonic treatment of material which is preliminarily saturated with solution of reagent (or water)inert to beneficial component and dissolving harmful admixtures. After discharge of leaching solution (or water), beneficial component is leached-out by leaching solution till reduction of its concentration in productive solution corresponding to maximum level obtained during standard leaching-out process. Then periodic ultrasonic treatment of material is performed again at contact with leaching solution till concentration of beneficial component in productive solution gets equal to permissible level for reworking of this solution in settling plant. Periodicity of ultrasonic treatment is determined by special relationship; radiators are mounted in cylindrical cavities (wells) or on surface of material. ^ EFFECT: enhanced intensification and efficiency due to increased rate of extraction of beneficial components; reduced consumption of reagents. ^ 5 cl, 3 dwg,1 ex |
