Title
(EN) BATTERY RECYCLING BY HYDROGEN GAS INJECTION IN LEACH
(FR) RECYCLAGE DE BATTERIE PAR INJECTION D'HYDROGÈNE GAZEUX DANS UN LIXIVIAT
Abstract
(EN)
The present invention relates to a process for the recovery of transition metals from batteries comprising (a) treating a transition metal material with a leaching agent to yield a leach which contains dissolved salts of nickel and/or cobalt, (b) injecting hydrogen gas in the leach at a temperature above 100 °C and a partial pressure above 5 bar to precipitate nickel and/or cobalt in elemental form, and (c) separation of the precipitate obtained in step (b).
(FR)
La présente invention concerne un procédé de récupération de métaux de transition à partir de batteries, comprenant (a) le traitement d'un matériau à base de métal de transition avec un agent de lixiviation pour produire un lixiviat qui contient des sels dissous de nickel et/ou de cobalt, (b) l'injection d'hydrogène gazeux dans le lixiviat à une température supérieure à 100 °C et à une pression partielle supérieure à 5 bars pour précipiter le nickel et/ou le cobalt sous forme élémentaire et (c) la séparation du précipité obtenu à l'étape (b).
