摘要

A method for extracting cobalt from copper raffinate. First, a supply of raffinate containing at least cobalt, copper, ferric iron and nickel, is provided. The raffinate is pretreated by one or all of raising the raffinate pH level; removing solids; and, reducing ferric iron to ferrous iron. Substantially all copper is removed using first ion exchange resin selective for copper. A second ion exchange resin selective for both cobalt and nickel is used to remove the cobalt and nickel. Cobalt and nickel are separately eluted from the second ion exchange resin.
