Oxidative stripping process for the recovery of uranium from wet-process phosphoric acid

Creators

Description

The present invention is a two-cycle liquid-liquid extraction process in which the uranium, as uranous ion, is extracted with a first-cycle extractant and then oxidatively stripped with a concentrated phosphoric acid solution. This uranium-enriched strip solution then serves as feed for a second liquid-liquid solvent extraction cycle where uranyl ions are extracted into an organic phase, stripped from the organic phase with ammonium carbonate soluton, and recovered as a high-grade u3O8 product.
