07.02.2010· Michael S. Moats, William G. Davenport, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.2.5.2 Solution Purification. The nickel and cobalt contained in the pregnant leach solutions from leaching of sulfide intermediates need to be separated prior to metal recovery by either electrowinning or hydrogen reduction. The most common modern method to do this is solvent extraction.
