OSTI ID:5521348
A process to maintain a high Fe/sup 2 +//Fe/sup 3 +/ concentration in the reductive stripping system for recovering uranium from wet-process phosphoric acid, comprises contacting partially oxidized strip acid, containing substantial amounts of Fe/sup 3 +/ which had just previously stripped uranium values from an organic solvent, with elemental iron to reduce Fe/sup 3 +/ to Fe/sup 2 +/ and provide a Fe/sup +2//Fe/sup 0/ conversion ratio of from about 1.5 to 3.0.
