FIELD: process engineering.
SUBSTANCE: invention relates to dressing of mineral resources. proposed method comprises crushing, pre-sizing, desludging of mesh minus, pre-sizing by sludge flotation to produce froth dump sludge and chamber product, grinding mesh plus of pre-sizing product and check screen sizing, combining mesh minus with chamber product of sludge flotation to form ore suspension to be directed to potassium chloride flotation. Mesh minus of check sizing is subjected to treatment by organic agent-depressor - "КС-МФ" in amount of 300 g/t and, further on, combined flow of ore suspension is directed for conditioning with amine emulsion before potassium chloride flotation.
EFFECT: higher efficiency.
