METHOD OF PRODUCING POTASSIUM CHLORIDE Russian patent published in 2015 - IPC C01D3/08

Abstract RU 2552459 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. A method of producing potassium chloride includes dissolving raw material in hot liquor, removing impurities from the hot saturated solution, crystallising the obtained suspension in a controlled vacuum-crystallisation apparatus, dehydrating and drying. During crystallisation, the suspension is subjected to ultrasonic treatment in the frequency range of 10-44 kHz with intensity of 0.1-25 W/cm².

EFFECT: invention enables to obtain a fine- or medium-grained product while enabling control of the average particle size in the range of 0,13-0,72 mm.
