Abstract

The process of phosphate rock’s decomposition by means of spent sulphuric acid was investigated. The basic parameters of the main technological stages, such as unit consumption and optimum concentration of sulphuric acid in decomposition of Karatau and Vyatka-Kama deposit’s phosphate rocks, process’s temperature and duration, were determined. A conventional ammonium superphosphate was obtained.
