PROCESSES FOR RECOVERING RARE EARTH ELEMENTS FROM VARIOUS ORES

摘要

The present disclosure relates to processes for recovering at least one rare earth element and/or at least one rare metal chosen from In, Zr, Li and Ga from at least one material. The process comprises:
leaching said at least one material to obtain a leachate comprising metal ions, said at least one rare earth element and/or said at least one rare metal, and a solid, and separating said leachate from said solid;
selectively removing said first metal ion from said leachate, thereby obtaining a composition comprising said second metal ion and said at least one rare earth element and/or said at least one rare metal, wherein said first metal ion is at least one aluminum ion and is removed from said leachate by selectively precipitating it under the form of AlCl 3 and removing it therefrom;
selectively at least partially removing said second metal ion from said composition, thereby obtaining a liquor comprising said at least one rare earth element and/or said at least one rare metal; and
selectively removing said at least one rare earth element and/or at least one rare metal from said liquor.
