FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Method for producing potassium chloride by dissolution and crystallization involves drying the wet concentrate to produce a dust-free product and a dust fraction. Dedusted product is conditioned with reagents. Dust fraction is briquetted at a weight ratio of 0.3 to 5 fractions from 0.1 to 0.2 mm to a fraction of less than 0.1 mm.
EFFECT: invention allows to improve the physical and mechanical properties of the produced potassium chloride and reduce the cost of its production, expand the range of products.
