摘要： A method for recovering nickel and cobalt from a product liquor solution by processing the product liquor solution through a continuous ion exchange process including a plurality of ion exchange beds containing nickel selective ion exchange resin that pass through individual process zones as part of a nickel recovery circuit, wherein the method includes the following steps: (a) passing the product liquor solution through an ion exchange bed to load nickel onto the ion exchange resin and produce a cobalt-containing raffinate solution, (b) passing a sulfuric acid solution through the loaded ion exchange bed to strip nickel from the exchange resin and produce a nickel-containing eluate, (c) passing a rinse solution through the stripped ion exchange bed, (d) adjusting the pH of the cobalt-containing raffinate solution to a pH of at least 2.3, (e) passing the cobalt-containing raffinate solution through an ion exchange bed to pre-load cobalt on the ion exchange resin, (f) repeating step (a) though (e) until the cobalt concentration of the cobalt-containing raffinate solution increases to at least twice that of the product liquor solution, and (g) removing a first portion of the cobalt-containing raffinate solution of step (d) from the nickel recovery circuit for subsequent cobalt recovery, and (h) passing a second portion of the cobalt-containing raffinate solution from step (d) to step (e).
