Способ получения хлористого калия с низким содержанием пылевых фракций крупностью менее 0,1 мм в конечном концентрате, включающий процессы измельчения, обесшламливания и флотационного обогащения сильвинитов, отличающийся тем, что, с целью сокращения содержания пылевых фракций в конечном концентрате, вводятся операции классификации хвостов с возвратом крупной фракции в питание мельницы и чернового концентрата с выводом крупной фракции в конечный концентрат, а мелкой - на перечистку концентрата.A method for producing potassium chloride with a low content of dust fractions with a particle size of less than 0.1 mm in the final concentrate, including the processes of grinding, deslamination and flotation enrichment of sylvinites, characterized in that, in order to reduce the content of dust fractions in the final concentrate, tailings classification operations are introduced with return a large fraction into the feed of the mill and rough concentrate with the withdrawal of the large fraction into the final concentrate, and the small fraction to the purification of the concentrate.
