Abstract

a. Procédé de récupération d'uranium dans le procédé de fabrication d'acide phosphorique par voie humide. b. Procédé caractérise en ce que la purification est faite en mettant en contact une solution aqueuse d'acide phosphorique provenant d'un procédé par voie humide, avec un agent laveur composé essentiellement d'un hydrocarbure dont le point d'ébullition est compris entre 150 degrés C et 300 degrés C, on le fait réagir avec les contaminants formant la boue dans l'acide phosphorique, suivant une quantité efficace pour laver les produits de contamination formant la boue de l'acide phosphorique, donner une phase boueuse et une phase d'acide phosphorique purifié, puis on extrait la phase boueuse.
