PHYSICO-CHEMICAL CHARACTERISTICS OF WASHED BURNT PHOSPHORIC ACID ENRICHED WITH EXTRACTION PHOSPHORIC ACID OF CENTRAL KYZYLKUM

The aim of the re is to enrich the washed burnt phosphor concentrate of Central Kyzylkums with extraction phosphoric acid. Optimal technological parameters of enrichment have been established, at which there is no loss of P2O5 of raw materials. During enrichment, the content of sulfate ions and fluorine compounds in the acid decreases and the acid is enriched with calcium ions from phosphorite.The effect of processing on the enrichment process has been proved by chemical analysis and confirmed by X-ray, IR spectroscopy and the use of a scanning electron microscope by comparing the characteristics of the initial and enriched phosphorite.
