Abstract
Le zinc et le plomb sont généralement présents de façon concomitante dans les minerais et les résidus de Zn-Pb. Un nouveau procédé hydrométallurgique non polluant permettant de lixivier et de récupérer sélectivement le zinc (Zn) à partir d'un minéral composite contenant du sulfure de zinc et de plomb (Pb), d'une roche broyée et non traitée ou de particules minérales non consolidées, de résidus de traitement et/ou d'un déchet contenant du zinc sulfuré aggloméré ou non aggloméré sans nécessiter une opération de fusion et de raffinage, a été développé. Cette technologie peut être utilisée soit in situ, soit ex situ sur la base de la susceptibilité d'un type particulier de dépôt minéral ou de minerai pour fours Martin. Un procédé et une composition d'agent de lixiviation sont utilisés pour permettre une lixiviation sélective du zinc à partir de mélanges et de minerais contenant du sulfure de zinc. Ledit procédé consiste à mettre en contact le mélange ou le minerai avec un agent de lixiviation aqueux comprenant : 1) un oxydant sélectionné pour oxyder le soufre présent uniquement dans le soufre élémentaire ; et 2) un hydroxyde de métal alcalin en quantités suffisantes pour former un zincate de métal alcalin soluble ; à prolonger le temps de contact entre l'agent de lixiviation et les solides pour obtenir la récupération de zinc souhaitée et la sélectivité dans le lixiviat souhaitée tout en faisant en sorte que les concentrations de réactifs restent opérationnelles ; à séparer le lixiviat souhaité des solides résiduels ; et à récupérer le zinc à partir du lixiviat.
