Study Of The Constant Of Phosphoric Acid Decomposition Of Phosphorite Flour From Phosphorites Of The Central Kyzylkum
Abstract
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.
