Processes for the recovery of gold and/or silver from lixiviant solutions include a preliminary step of: (a) contacting the lixiviant solution with ion exchange resins containing amine functionality, optionally dispersed or distributed within a polyurethane matrix and/or in the presence of an alcohol that is substantially insoluble in the lixiviant solution, or (b) contacting the lixiviant solution with a liquid extractant in the presence of an alcohol that is substantially insoluble in the lixiviant solution. The ion exchange resin or extractant, once loaded with silver and/or gold, is then separated from the lixiviant solution, and eluted to recover the gold and/or silver values.

Procédé servant à récupérer de l'or ou de l'argent depuis des solutions de lixiviation et comprenant une étape préliminaire consistant à: (a) mettre en contact la solution de lixiviation avec des résines échangeuses d'ions contenant une fonctionnalité amine, soit éventuellement dispersée ou répartie à l'intérieur d'une matrice de polyuréthanne, soit en présence d'un alcool pratiquement insoluble dans la solution de lixiviation; (b) mettre en contact la solution de lixiviation avec un extracteur de liquide en présence d'un alcool pratiquement insoluble dans la solution de lixiviation. On sépare ensuite la résine échangeuse d'ions ou l'extracteur de la solution de lixiviation, une fois qu'ils sont chargés d'argent ou d'or, et on les élue afin de récupérer l'or ou l'argent.
