FIELD: mining.
SUBSTANCE: invention relates to beneficiation of minerals and can be used for flotation of gold-bearing ores. Proposed method comprises conditioning of initial raw material with reagents with at least a foaming agent, introduction of supersaturated steam and gas into pulp in form of aerosol jet and removal of separation products. Before introduction into pulp of steam and gas, ice is added thereto in amount of 25.0-45.0 kg/m3. Supersaturated steam is introduced into gas flow in a pulsed manner with frequency equal to 160-200 Hz.
EFFECT: increased extraction of valuable components into commercial product and its quality in concentration of ores by flotation.
