Abstract

L'invention s'applique à la récupération de métaux comprenant l'or, l'argent, le cuivre et le nickel adsorbés sur un support tel que du carbone actif sous la forme d'un complexe ionique de métal alcalino-terreux dont la partie anionique comprend le métal à récupérer. Le procédé consiste à mettre le support en contact avec une solution d'un cyanure de métal alcalin, d'un hydroxyde de métal alcalin ou de ces deux composés puis d'effectuer la désorption du support par de l'eau à faible concentration en cations de métal pour obtenir par exemple la courbe 17 de la concentration en or de l'éluat en fonction du nombre de volumes de lit utilisé pour l'élution, les courbes 15 et 16 correspondant à d'autres procédés moins favorables.
