Abstract
La présente invention se rapporte à un procédé d'extraction d'un ou de plusieurs métaux M choisis parmi l'or et les métaux du groupe du platine contenus dans une phase aqueuse acide A1. Ce procédé comprend les étapes suivantes : (a) une mise en contact de la phase aqueuse acide A1 avec une phase A2 non miscible à l'eau, moyennant quoi on obtient, après séparation de phases, une phase aqueuse A1' et une phase A2' comprenant le ou les métaux M ; puis (b) une collecte de la phase A2'. La phase A2 est choisie parmi une phase A21 comprenant un malonamide et un liquide ionique LI, et une phase A22 comprenant un liquide ionique fonctionnalisé LIF comprenant un groupe malonamide. L'invention se rapporte également à un procédé de récupération du ou des métaux M qui met en œuvre ce procédé d'extraction. Pas de figure.
