This process recovers uranium using a liguid-liquid extracting process for phoshoric acid. In the first cycle, the impure phoshoric acid with dialkylphoshoric acid, 3-alkyl-phoshine oxide and inactive diluent, the phase in separated. By treating the orgaic state with uranium in phosphoric acid having Fe++, the organic state that is short of uranium, is recycled through the extraction process. By extracting the multiplier in the inactive diluent, di-alkyl phosporic acid, 3-alkylphoshine-oxide, etc., it gives on organic state that is short of uranium and a state rich in uranium. When the 1st cycle organic state is corrected and cleaned, uranium is produced.
