A method for recovering at least one metallic element from ore or other material is described and includes reacting ore or other material with a salt capable of recovering the metallic element from the ore or other material to form a reaction product that includes the metallic element. The method also includes recovering the metallic element from the reaction product. To remove the metallic element from the reaction product, the method can involve crushing the reaction product to form a crushed material and dissolving the crushed material in a solvent to remove the precipitates, thereby leaving a sulfate solution containing the metallic element. The method is particularly directed to the recovery of cesium from silicate- or aluminosilicate-based ore like pollucite via clinker formation by reacting the ore at elevated temperature in the presence of a metal sulfate salt.
Procédés de récupération d'au moins un élément métallique à partir de minerai ou d'une autre matière, qui consiste à mettre en réaction le minerai ou l'autre matière avec un sel capable de récupérer l'élément métallique à partir du minerai ou de l'autre matière pour former un produit de réaction contenant l'élément métallique. Ledit procédé consiste également à récupérer l'élément métallique à partir du produit de réaction. En vue de la récupération de l'élément métallique à partir du produit de réaction, ledit procédé peut comporter le broyage du produit de réaction pour obtenir un produit broyé et la dissolution de la matière broyée dans un solvant pour extraire les précipités, ce qui permet d'obtenir une solution de sulfate contenant l'élément métallique.
