Abstract

Procédé de récupération de métaux précieux du type or et argent à partir de solution aqueuse sous forme de solide: mélange de solution aqueuse (par exemple, agent de lixiviation au thiosulfate ou au thiocyanate) contenant des métaux précieux avec des ions ferreux en présence d'une quantité efficace d'ions hydroxyde. Les ions de métaux précieux sont réduits et ils co-précipitent avec les hydroxydes de fer et/ou les oxydes de fer hydratés. On récupère et on purifie le co-précipitat. La désoxygénation de la solution de réaction est facultative. Il s'agit d'un procédé de récupération rapide complet et propre.
