Abstract

a. Procédé d'extraction de métal par lixiviation in situ. b. Procédé caractérisé en ce qu'on met en contact le métal noble avec une solution de lixiviation contenant une sorte d'ion assurant la solubilisation de ce métal, la solubilisation réduisant la concentration de la sorte d'ion efficace, puis on reprend la solution de lixiviation chargée, on récupère le métal noble à partir de cette solution chargée, et on met en contact la solution de lixiviation avec une résine échangeuse d'ions sous la forme de la sorte d'ions efficace de façon à augmenter la concentration qui avait été réduite. c. Procédé applicable à l'extraction d'uranium.
