FIELD: mineral dressing. SUBSTANCE: ore is disintegrated to particle size 0.2-0.8 mm and collector is added. Mineral constituents of ore are separated by floatation technique. Anhydrous plaster, water-insoluble clay minerals, and halite are separated into foam product, and carnallite is separated into chamber product. As collector, hydroxyethylated alcohols or hydroxyethylated fatty acids and alkylmorpholin in proportion from 1:2.5 to 1:20 are used. To provide required proportion of potassium and magnesium chlorides in final product, into chamber product of floatation, silvite is additionally separated.
