Cobalt recovery by solvent extraction from acid leach solutions of Caron's process mixed Ni/Co sulfide

摘要

This paper presents a summary of the results for the selective recovery of cobalt by solvent extraction using Cyanex 272 extractant from solutions produced by acid leaching of nickel/cobalt sulfides product of the Caron's process. Data from laboratory and miniplant tests using basic nickel carbonate acid leaching solution as aqueous feed are also presented.
