FIELD: inorganic compounds technology.
SUBSTANCE: invention relates to production of strontium compounds and can be used in manufacture of complex fertilizers. Apatite is decomposed by nitric acid, nitric acid extract is diluted with water, concentrated, and filtered. Consumption of water 0.03-0.12 t per 1 t apatite is maintained in apatite decomposition reactor.
EFFECT: reduced loss of strontium nitrate with clarified solution more by 20% during operation under optimum conditions.
