FIELD: metallurgy.
SUBSTANCE: method includes preparation of leaching solution with usage of metal-bearing mine water, its collection up to volume required for implementation of leaching process. Additionally it is implemented anlage of sulfide-bearing wastes into underground cavities of waste mine openings and it is heated leaching solution by heat of subsoils in tank constructed lower than subsurface voids of waste mine openings. After leaching it is implemented irrigation of sulfide-bearing wastes by leaching solution, collection and recovery of productive solution.
EFFECT: reduction of expenditures for leaching of sulfide-bearing wastes and elimination of expropriation of considerable areas of Earth for storages of wastes.
