Application of X-ray fluorescence analysis for control of P205 content in phosphate flour

Abstract

Control of phosphoric anhydride P₂0₅ content in phosphate rock is one of the most important stages of the technological process of phosphate flour production. At present, the determination of P₂0₅ content in production conditions is mainly carried out by methods of chemical analysis (weight, photocolorimetric and ionic), involving the transfer of phosphorite sample into solution and subsequent determination of phosphorus content in terms of P₂0₅.
