Patent

CA 2424372

A method for the recovery of a metal from a liquid medium containing the metal I solution or in finely divided insoluble from comprises contacting the medium with a functionalised polymer fibre capable of binding the metal and recovering the metal from the fibre. The polymer fibre is suitably a polyolefin, a fluorinated polyethylene, cellulose or viscose, which is functionalised by the radiation grafting of at least one monomer. The method is particularly suitable for the recovery of platinum group metals from process residues.

L'invention concerne un procédé de récupération de métaux à partir d'un milieu liquide contenant le métal en solution ou sous forme finement divisée insoluble, consistant à mettre le milieu en contact avec une fibre polymère fonctionnalisée capable de fixer le métal et à récupérer le métal à partir de ladite fibre. La fibre polymère est avantageusement une polyoléfine, un polyéthylène fluoré, de la cellulose ou de la viscose, fonctionnalisé par greffe sous rayonnement d'au moins un monomère. Ce procédé est particulièrement adapté pour la récupération de métaux du groupe des platines à partir de résidus de traitement.
