Japanese Patent JPS563416
Kind Code:
B2
Abstract:
A process for the recovery of uranium from a wet-process type phosphoric acid solution is effected by adjusting said solution with sufficient ferrous ion to insure that the uranium is in the uranous form, contacting the adjusted solution with an organic phase consisting essentially of a mono and disubstituted phenyl ester of orthophosphoric acid dissolved in an inert diluent to effect transfer of the uranium into the organic phase, stripping the uranium from the organic phase with a 6-12 M phosphoric acid solution containing an oxidizing agent to produce a uranyl phosphate strip solution more highly concentrated in uranium than the wet-process feed solution.
