Separation process for the recovery of uranium from wet-process phosphoric acid
Patent
·
OSTI ID:5621044
A synergistic extractant combination consisting of di(2-ethylhexyl) phosphoric acid (D2EHPA) and dibutyl butyl phosphonate (DBBP) in kerosene is employed in a two-cycle separation process for the recovery of uranium from wet-process phosphoric acid. The addition of the sulfuric acid and water scrubbing steps for the recycled extractant provides no disadvantages with respect to the comtamination and dilution by the ammonium ion and water to the phosphoric acid and also no precipitation occurs in the second cycle extraction step. The advantages of this process are lower chemical cost, higher product purity and better phase separation in comparison with the previous process.
