Methods for inhibiting depletion of metal values from pregnant lixiviant solutions comprise contacting the requisite metal ore with a prep-robbing inhibition agent (PRIA) comprising one of: (I) alkyl polyglucoside surfactants; (II) imidazoline based amphoteric surfactants; (III) hydroformylation products of lower (C2-C8) alkanes in an organic solvent medium, and (IV) esters and aldehydes. The method is particularly effective in heap leaching of gold with a cyanide lixiviant.

L'invention concerne des procédés d'inhibition de l'épuisement en produits métalliques précieux de solutions de lixiviation enrichies consistant à contacter le minerai voulu avec un agent d'inhibition d'épuisement de solutions déjà enrichies contenant un composé parmi: (I) des tensioactifs alkyl polyglucoside; (II) des tensioactifs amphotères à base d'imidazoline; (III) des produits d'hydroformylation d'alcanes inférieurs (C¿2?-C¿8?) dans un solvant organique, et (IV) des esters et des aldéhydes. Ce procédé est particulièrement efficace dans le lessivage de déblais d'or avec un agent de lixiviation au cyanure.
