Title
(EN) METHOD FOR RECOVERING NOBLE METALS AND OTHER BYPRODUCTS FROM ORE
(FR) PROCÉDÉ DE RÉCUPÉRATION DE MÉTAUX NOBLES ET D'AUTRES SOUS-PRODUITS À PARTIR D'UN MINERAI
Abstract
(EN) Method for the recovery of noble metals comprising the steps of subjecting ore particles to an electrolytic bath (1) enhanced by an ultrasonic bath (2), the electrolytic bath (1) comprising heavy and/or semi-heavy water; shock heating the ore particles for disintegrating them; and separating noble metals from the remains of said disintegrated ore particles.
(FR) La présente invention concerne un procédé de récupération de métaux nobles comprenant les étapes consistant à soumettre des particules de minerai à un bain électrolytique (1) amélioré par un bain ultrasonique (2), le bain électrolytique (1) comprenant de l'eau lourde et/ou semi-lourde, à chauffer par ondes de choc les particules de minerai pour les désintégrer, et à séparer les métaux nobles du reste desdites particules de minerai désintégrées.
