STUDY OF THE INFLUENCE OF NITRIC ACID ENRICHMENT OF PHOSPHORITES OF THE CENTRAL KYZYLKUM ON THE PROCESS OF OBTAINING PHOSPHORUS-CONTAINING FERTILIZERS BASED ON THEM

Abstract

An analysis of the literature shows that natural phosphates are suitable for de-composition with nitric acid, which does not contain significant amounts of cal-cium carbonate, magnesium carbonate and silicates, iron and aluminium com-pounds, which are easily decomposable acids, and as a result, complicate the processing of phosphates and degrade the quality of fertilizers. The best way to obtain phosphorus-containing fertilizers is the phosphoric acid decomposition of phosphate raw materials.
