ABSTRACT:
A process for recovering uranium contained in phosphated solutions including the steps of contacting the solution with a diester of pyrophosphoric acid, reextracting the uranium with an alkaline solution, precipitating the uranium, acidifying and agitating the resulting product, separating the organic phase from the aqueous phase and recycling the organic phase to the initial contacting step. The precipitate is separated prior to recycling.
