Abstract

Le procédé décrit permet de récupérer des métaux à partir dun déchet radioactif solide, de préférence de luranium, du césium, du mercure, du thorium, des terres rares ou des combinaisons de ceux-ci. Le procédé comprend une étape de lixiviation et une étape de séparation. Létape de lixiviation consiste à mettre le déchet radioactif solide en contact avec un acide inorganique aqueux et un sel de lixiviation pour produire un mélange dun lixiviat riche en métal et dun déchet pauvre en métal, qui sont séparés au cours de létape de séparation. Un procédé pour récupérer des métaux à partir dun déchet radioactif solide comprenant une étape dattrition, une étape de lixiviation, une étape de lavage, une étape de combinaison et une étape de récupération est également décrit.
