Abstract

La présente invention concerne un procédé pour la récupération sélective d'au moins un élément du groupe des chalcophiles (« CPM »), ainsi que défini par les présentes, dans un matériau contenant le CPM et un ou plusieurs éléments non chalcophiles (« NCE »), ainsi que défini par les présentes, ledit procédé comprenant les étapes consistant : à mettre en contact le matériau avec une solution alcaline contenant un lixiviant comprenant un acide aminé ou un dérivé de celui-ci, afin de lixivier sélectivement le CPM du matériau et produire un lixiviat contenant du CPM et un résidu contenant des NCE ; à récupérer le CPM dans le lixiviat.
