Abstract

The purpose of the research is to establish the optimal technological parameters for the decomposition of the washed burnt phosphate concentrate (WBPC) of the Central Kyzylkum (CK) with nitric acid, to study the chemical composition, rheological properties, the degree of pulp clarification and the filtration rate of the thickened part of the pulp. The decomposition coefficients of WBPC and the pH of the nitric acid extract were determined depending on the norm of the acid and the S:L medium. The chemical and mineralogical composition of the solid phase formed after filtration of the thickened pulp has been established. Compiled material balance of the process of decomposition of WBPC nitric acid.
