FIELD: technological processes.
SUBSTANCE: invention relates to means of dry concentration of mineral raw materials. Device for dry enrichment of gold-bearing ores contains a raw material supply unit, a raw material particles acceleration unit and a ready product reception unit. Unit for acceleration of particles of raw material is made in the form of drum equipped with blades and connected to shaft of electric motor. Finished product reception unit is made of perforated sheets with air-permeable coating.
EFFECT: reduction of losses of fine fractions of gold at enrichment of gold-bearing ores, and also reduction of power inputs and increase of labour productivity.
