HYDROMETALLURGICAL EXTRACTION OF COPPER, ZINC AND COBALT FROM ORES CONTAINING MANGANESE DIOXIDE

摘要

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.
