Abstract

L'invention concerne un procédé permettant d'extraire des composés d'uranium à partir de l'acide phosphorique par voie humide, qui consiste notamment à abaisser la teneur en fer de l'acide phosphorique par voie humide et à réduire la valence de tout fer ferrique restant dans l'acide phosphorique par voie humide en fer ferreux, puis à extraire les composés d'uranium de l'acide phosphorique par voie humide. Le procédé peut consister notamment à séparer un flux latéral d'un flux d'alimentation de l'acide phosphorique par voie humide, le flux latéral présentant une teneur plus élevée en composés d'uranium que le flux d'alimentation par filtrage. L'extraction de composés d'uranium de l'acide phosphorique par voie humide peut se réaliser par un procédé d'échange ionique ou par extraction par solvant.
