FIELD: potassium chloride production.
SUBSTANCE: claimed method includes crushing, deslurring, sylvinite flotation concentration, and particle size classification of flotation concentrate. To reduce dust fraction quantity in commercial concentrate said fractions are isolated in classification process, aqueous solution thereof is prepared, wherein abovementioned solution has potassium chloride/water mass ratio more than 17 %, and obtained solution is recycled into grinder. Method of present invention makes it possible to reduce dust fraction of size less than 0.1 mum in fine-grained potassium chloride.
EFFECT: improved method for potassium chloride production with low content of dust fractions.
