FIELD: mining.
SUBSTANCE: invention relates to dressing of minerals and can be used for dressing of rare metals dressing. Claimed process comprises the initial pulp desliming, pulp conditioning with soda ash and tail oil sodium soap at pulp density of 30% solid and flotation of tungsten minerals. Prior to feeding of soda ash and tail oil sodium soap, aqueous solution of caustic soda is added at the ratio of soda ash, caustic soda and tail oil sodium soap of 500:150:200 to 500:250:200. Flotation is executed at water temperature of 20-8°C.
EFFECT: higher yield at flotation in cold pulp.
