A process for recovering a target metal from an oxidised metalliferous material comprises the steps of: - in a leaching stage, leaching the oxidised metalliferous material with an acidic aqueous halide solution to leach the target metal into solution, the leaching solution being generated by adding sulfuric acid to a solution comprising a metal halide; - passing the solution from the leaching stage to a target metal recovery stage in which the target metal is recovered from the solution whilst the metal halide is retained in solution; and - returning the solution with the metal halide therein from the target metal recovery stage to the leaching stage.

L'invention concerne un procédé pour récupérer un métal cible à partir de matériaux métallifères oxydés comprenant les étapes suivantes : une étape de lessivage, dans laquelle le matériau métallifère oxydé est lessivé au moyen d'une solution d'halogénures aqueuse, ce qui permet de lessiver le métal cible dans la solution, cette dernière étant produite par addition d'acide sulfurique à une solution comprenant un halogénure métallique ; passage de la solution de l'étape de lessivage à une étape de récupération du métal cible, dans laquelle le métal cible est récupéré à partir de la solution, tandis que l'halogénure de métal est retenu dans la solution ; et retour de la solution comprenant l'halogénure de métal de l'étape de récupération de métal cible vers l'étape de lessivage.
