FIELD: concentration of noble metals; may be used in recovery of gold and metals of platinum group from blown off heavy concentrate. SUBSTANCE: method includes pneumatic treatment of placer gold to produce gold and blown off heavy concentrate and their conditioning. Novelty consists in that conditioning of blow off heavy concentrates is effected by flotation selection with production of gold concentrate directed for refining, concentrate of platinum group metals directed for cyaniding, and selection tailings returned for repeated concentration. Flotation selection is carried out at pulp density of 40-60%, consumption of collector in the amount of 0.005-0.020 g and consumption of forming agent in the amount of 0.003-0.010 g per gram of noble metal. EFFECT: production of commercial products from blowing off materials.
