FIELD: methods for production of potassium chlorides. SUBSTANCE: method for production of potassium chloride includes flotation of sylvinites with grains sizing less than 1 mm, drying and classification of finished product into close-grained and dusty potassium chloride. In course of flotation added to dusty fraction sizing less than 0.2 mm to the first cell of flotation machine is collector within 20-30% of its total consumption. Amine content in dusty fractions is reduced by two times. EFFECT: higher efficiency.
