Abstract
Procédé d'élimination du cadmium contenu dans l'acide phosphorique de voie humide par flottation au moyen d'un agent tensioactif anionique collecteur du cadmium et d'un gaz injecté, en présence d'autres impuretés dont le fer et éventuellement de l'uranium qui se caractérise en ce que dans le but d'améliorer l'élimination du cadmium, on effectue la réduction du fer contenu dans l'acide phosphorique à l'état trivalent pour la conduire à l'état divalent avant d'introduire le collecteur du cadmium dans le milieu à purifier par flottation. L'agent collecteur est choisi dans le groupe des acides esters dithiophosphoriques ou de leurs sels alcalins.
