This article presents the results of laboratory studies to study the decomposition constant of Kyzylkum phosphorite flour with evaporated extraction phosphoric acid of various concentrations (35,69; 41,20; 44,98% Р2О5) at high norm and temperature 70-100 °C during 5-120 minutes. It was shown that the maximum value of the decomposition coefficient of phosphorite flour (Kdecom. 99.95%) is achieved using phosphoric acid with a content of 35, 69% Р2О5.
