OBTANING OF AMMONIUM PHOSPHATES HIGH-QUALITY FROM EXTRACTIVE PHOSPHORIC ACID ON THE BASIS OF CENTRAL KYZYKUM PHOSPHORITES

This paper presents data on the study of the processes of obtaining high-quality water-soluble ammonium phosphates by partial purification of phosphoric acid during extraction and complete purification during ammonization of wet-process phosphoric acid. As a result, products containing ~52% P2O5 and ~12% N were obtained, while reducing the fluorine content to 0.8-1.0%. The resulting products are completely water-soluble nitrogen-phosphorus fertilizers and are used as fertilizers for growing crops by drip irrigation and hydroponics."Science and innovation" international scientific journal.
