FIELD: flotation concentration of potassium salts. SUBSTANCE: for flotation of coarse-grained sylvite the following reagent-collector is used: a mixture of carboxylic acid hydrazides, and flotation is carried out in the presence of hydrochloric acid of the general formula 
, where R - a hydrocarbon radical with 7-12 carbon atoms. Flotation is carried out in the presence of hydrochloric acid taken at concentration 150-200 g/t. Granulometric composition of potassium chloride obtained is up to 1.6 mm, it has high quality of rough concentrate by potassium chloride (92± 2)%. EFFECT: increased extraction of KCl by 1-5%. 2 tbl
