Abstract

L'invention concerne un nouveau procédé permettant de traiter un échantillon minéral. Les étapes de ce procédé consistent à introduire conjointement un échantillon de minerai fragmenté et un fondant dans une cuve à réaction, le fondant comprenant un agent collecteur conçu pour collecter un constituant de l'échantillon de minerai pendant la fusion, à faire fondre le fondant et l'échantillon de minerai de manière à obtenir un laitier en fusion et un agent collecteur en fusion, à préchauffer une cuve de séparation, à introduire le laitier en fusion et l'agent collecteur en fusion dans la cuve de séparation préchauffée, et à séparer le laitier en fusion de l'agent collecteur en fusion.
