FIELD: production of strontium salts from lean celestine ores. SUBSTANCE: method for extraction of strontium from celestine ores includes treatment of celectine with soda solution, separation of carbonate product and its treatment with nitric acid with concentration of 3.0-3.5 mas. taken at ratio HNO3:SrCO3= (1,5-1,8):1= (1.5-1.8):1 and obtaining solution of strontium nitrate. Method allows high degree of extraction of strontium 85.5% from lean ore. EFFECT: higher degree of extraction of strontium in processing celestine ores containing 20.87% of strontium sulfate. 1 tbl
