FIELD: mining.
SUBSTANCE: method to produce metals from storages of stale wastes of polymetal ore dressing consists in trench opening of the storage, detection of layers containing easily dissolved forms of non-ferrous metals and layers containing noble metals, bulk extraction of stale wastes from the storage, fraction separation of stale wastes into a finer sulfide fraction dressed with noble metals and coarser fraction dressed with non-ferrous metals, and their separate leaching.
EFFECT: complete processing of storages of stale dressing wastes, release of areas occupied by them, complex usage of mineral materials and high environmental and economic effect.
