Title (EN) HYDROMETALLURGICAL EXTRACTION OF COPPER, ZINC AND COBALT FROM ORES CONTAINING MANGANESE DIOXIDE
(FR) EXTRACTION HYDROMETALLURGIQUE DE CUIVRE, DE ZINC ET DE COBALT A PARTIR DE MINERAIS CONTENANT DU DIOXYDE DE MANGANESE
Abstract: front page image
(EN)A method is provided for extracting copper, cobalt and zinc from an ore containing those metals and manganese dioxide. The ore is subjected to an acid, oxidizing leach followed by an acid, reducing leach. Solids are separated from the leachate and the leachate liquid is subjected to solvent extraction steps, to sequentially remove copper, zinc and cobalt in that order.
(FR)L'invention concerne un procédé pour extraire du cuivre, du cobalt et du zinc d'un minerai contenant ces métaux ainsi que du dioxyde de manganèse. Ce minerai est soumis à une lixivation acide oxydante suivie d'une lixivation acide réductrice. Les solides sont séparés de la solution de lixivation et le liquide de la solution de lixivation est soumis à plusieurs étapes d'extraction par solvant, afin d'éliminer successivement le cuivre, le zinc et le cobalt, dans cet ordre.
