PROCESS FOR RECOVERING URANIUM FROM WET-PROCESS PHOSPHORIC ACID |
摘要 |
<p>PROCESS FOR RECOVERING URANIUM FROM WET-PROCESS PHOSPHORIC ACID A process for recovering uranium from a wet-process phosphoric acid crude solution is provided in which the phosphoric acid crude solution is contacted with an organic extractant consisting of octylphenyl phosphoric acid, di(2-ethylhexyl) phosphoric acid and trioctylphosphine oxide dissolved in an organic diluent to extract uranium from the phosphoric acid crude solution. The thus uranium loaded organic extractant is then contacted with mixed acid consisting of hydrofluoric acid and sulfuric acid, or alternatively with concentrated phosphoric acid to back-extract the uranium from the organic extractant.</p> |
