The phosphoric acid formed after treating uraniumbearing phosphate rocks with acids contains, in addition to uranium, impurities such as Ca, Fe, Al, and Si fluorides. The solutions have a high specific gravity, a low emf, and a tendency to form deposits upon standing. The usual extraction agents, such as ketones and simple esters cannot be used for extracting the uranium. It was found that single acid esters of ortho and pyrophosphoric acids and their mixtures with neutral esters are quite effective. For industrial application the ester of di-alkyl pyrophosphoric acid and mixtures of di-alkyl orthophosphoric esters with alkyl-dialkylphosphoric esters appear to be most promising. 21 references are given.
