METHOD OF PRODUCING POTASSIUM CHLORIDE WITH LOW CONTENT OF DUST FRACTIONS WITH FINENESS BELOW ONE TENTH MM

摘要

FIELD: mining industry. SUBSTANCE: method including operations of division, desludging, flotation concentration of sylvinites, and sorting also involves sizing sylvite flotation tails and returning coarse fraction into mill feed. EFFECT: reduced content of dust fractions in divided sylvinite ore and increased yield of fractions with fineness higher than six tenth mm into final concentrate.
