Abstract

L'invention concerne un procédé de raffinage de boues produites au cours d'un processus de préparation de trifluorure d'azote par électrolyse, afin d'obtenir du nickel, et de production de produits métalliques en nickel à partir du nickel. Selon l'invention, des produits métalliques en nickel de grande pureté peuvent être produits à partir du nickel obtenu par raffinage des boues produites au cours d'un processus de préparation de trifluorure d'azote par électrolyse. Ainsi, du nickel sous forme de boues voué à être mis au rebut peut être réutilisé pour réduire la quantité de déchets et éviter efficacement une contamination environnementale causée par les déchets de boues de nickel.
