Title (EN) METAL RECOVERY FROM METALLURGICAL WASTE BY CHLORIDISING
(FR) PROCESSUS DE RECUPERATION DE METAL
Abstract:
(EN) A process for recovering a metal chloride or mixed metal chloride from a solid waste material comprising recoverable metal containing constituents produced by lead, copper or zinc smelting and refining processes, said process comprising the steps of: (i) heating the solid waste material; (ii) treating the heated material of step (i) with a gaseous chloride to form a gaseous metal chloride containing product;and (iii) treating the gaseous metal chloride containing product of step (ii) to recover the metal chloride or mixed metal chloride. The metal chloride may be further treated to extract the metal itself.
(FR) L'invention concerne un processus de récupération d'un chlorure métallique ou de chlorures métalliques mélangés, à partir de déchets solides à constituants contenant du métal récupérable, produits par des processus de fusion et d'affinage de plomb, de cuivre ou de zinc. Le processus selon l'invention consiste : (i) à chauffer les déchets solides ; (ii) à traiter le matériau chauffé issu de l'étape (i) au moyen d'un chlorure gazeux pour obtenir un produit contenant un chlorure métallique gazeux ; et (iii) à traiter le produit contenant un chlorure métallique gazeux issu de l'étape (ii) pour récupérer le chlorure métallique ou les chlorures métalliques mélangés. Le chlorure métallique peut ensuite être traité en vue de l'extraction du métal.
