Abstract

L'invention concerne également un procédé de récupération d'éléments de terres rares à partir d'un minerai contenant un élément de terres rares, le procédé comprenant les étapes consistant à : ajouter une quantité d'une source contenant du silicium au minerai contenant un élément de terres rares pour former un mélange ; soumettre le mélange à un procédé de cuisson acide, le mélange étant soumis à des températures supérieures à 150 °C ; et à effectuer un processus de lixiviation sur le mélange pour produire une liqueur d'attaque à une concentration élevée d'éléments de terres rares.
