URANIUM SOLVENT EXTRACTION METHOD |
摘要 |
<p>[Problem] To provide a uranium solvent extraction method capable of collecting uranium from a low concentration uranium exudate using a countercurrent extraction tower. [Solution] The uranium solvent extraction method comprises a process of extracting uranium in an exudate containing 50 - 800 ppm by weight of uranium into a solvent by bringing the exudate and the solvent into countercurrent contact in a countercurrent extraction tower in which the HTU based on raffinate is in the range of 1 - 5 m. The ratio (A/O ratio) of the supply flow for the exudate (A) with respect to the supply flow for the solvent (O) during same is 10 - 80.</p> |
