The purpose of the study is to develop an energy-saving technology for producing feed monocalcium phosphate by simultaneous concentration and deep defluoridation of extraction phosphoric acid in the presence of acid-soluble silicon oxide and decomposition of limestone with purified acid. Optimal technological parameters, methods of supplying coolant and types of evaporator, in which the degree of defluoridation is more than 99.0%, have been established. Feed monocalcium phosphate was obtained on its basis, their physicochemical characteristics were determined, technological schemes were developed and material balances were compiled.
