PURIFICATION OF PHOSPHORIC ACID BASED ON PHOSPHORITES OF CENTRAL KYZYL KUM IN THE PROCESS OF EXTRACTION WITH CALCIUM CARBONATE AND OBTAINING FROM A SINGLE PHOSPHORUS FERTILIZER

Аннотация

The work describes the processes of purification of phosphoric acid based on phosphorites of the Central Kyzylkum from impurities of fluorine and sulfates in the process of extraction with calcium carbonate and the production of single phosphorus fertilizer by neutralizing the purified acid with calcium carbonate
