Title (EN) METHOD AND SYSTEM FOR RECOVERING RARE EARTH ELEMENTS FROM WITHIN AN OBJECT
(FR) PROCEDE ET SYSTEME DE RECUPERATION DE TERRE RARE PRESENTE AU SEIN D'UN OBJET
Abstract:
(EN) The invention relates to a method and system for recovering at least rare earth elements from within an object A consisting of at least one first rare earth portion or a mixture of rare earth elements and a second metal portion. The invention is characterized in that it comprises a solvothermal treatment step that places the object in contact with a fluid for causing at least one rare earth portion and/or mixture of rare earth elements and the metal portion to oxidize in order to separate same, the value of the reaction temperature Tr is selected according to the nature of the object, the reaction following a R-M→ R(X)x+M(X)y scheme, where R is the rare earth element or a mixture of rare earth elements, M is the transition metal, and (X) is a group which depends on the fluid used.
(FR) Procédé et système pour récupérer au moins des terres rares contenues dans un objet A composé au moins d'une première partie terre rare ou d'un mélange de terres rares et d'une deuxième partie métallique caractérisé en ce qu'il comporte une étape de traitement solvothermal mettant en contact l'objet avec un fluide adapté à provoquer l'oxydation d'au moins une partie terre rare et/ou mélange de terres rares et de la partie métallique afin de les séparer, la valeur de la température de réaction Tr est choisie en fonction de la nature de l'objet, la réaction suivant un schéma R-M→ R(X)x+M(X)y avec R la terre rare ou un mélange terres rares, M le métal de transition, (X) un groupement fonction du fluide utilisé.
