Abstract

Procédé d'extraction d'uranium à partir d'acide phosphorique de voie humide selon lequel l'acide préalablement oxygé est traité par un solvant organique constitué par un mélange d'acide dialcoyle phosphorique et d'oxyde de trialcoylphosphine en solution dans un solvant inerte de façon à séparer l'acide phosphorique désuranié et un extrait organique contenant l'uranium que l'on sépare sous forme d'uranyle tricarbonate d'ammonium en traitant l'extrait organique dans un appareil de réextraction comportant au moins deux étages, à l'aide d'ammoniaque et d'une solution de carbonate d'ammonium injectés séparément dans les étages extrêmes, le solvant organique étant régénéré avant d'être recyclé, par traitement à l'aide d'un acide.
