Title (EN) COMPOSITION AND METHOD RELATED TO THE RECOVERY OF GERMANIUM AND RARE EARTH ELEMENTS
(FR) COMPOSITION ET PROCÉDÉ ASSOCIÉS À LA RÉCUPÉRATION DE GERMANIUM ET D'ÉLÉMENTS TERRES RARES
Abstract:
(EN) Disclosed herein is a method involving the steps of: a) mixing a first pond coal fly ash and a first ionic liquid, thereby leaching germanium from the first pond coal fly ash and producing a second pond coal fly ash and a first mixture comprising the first ionic liquid and the leached germanium: fa) separating the first mixture from the second pond coal fly ash; and c) mixing a first brine with the second pond coal fly ash, thereby leaching iron and one or more rare earth elements from the second pond coal fly ash and producing a third pond coal fly ash and a second mixture comprising the first brine and the leached iron and one or more rare earth elements.
(FR) La présente invention concerne un procédé comprenant les étapes de : a) mélange de premières cendres volantes de charbon de bassin et d'un premier liquide ionique, de manière à lixivier le germanium à partir des premières cendres volantes de charbon de bassin et produire des deuxièmes cendres volantes de charbon de bassin et un premier mélange comprenant le premier liquide ionique et le germanium lixivié; a) séparation du premier mélange des deuxièmes cendres volantes de charbon de bassin; et c) mélange d'une première saumure avec les deuxièmes cendres volantes de charbon de bassin, de manière à lixivier le fer et un ou plusieurs éléments terres rares à partir des deuxièmes cendres volantes de charbon de bassin et produire des troisièmes cendres volantes de charbon de bassin et un deuxième mélange comprenant la première saumure et le fer lixivié et un ou plusieurs éléments terres rares.
