摘要：
A process for separately recovering nickel and cobalt from solution includes adjusting the pH of the solution to a value between about 3 and about 6, and then contacting the solution with a chelating ion exchange resin having aminocarboxylic acid functional groups to selectively load nickel onto the resin to produce a nickel loaded resin and a nickel depleted cobalt containing solution. The process is also applicable to the separate recovery of copper and zinc from solution.
