Abstract
In an ion exchange process for recovering valuable components from a weak feed solution containing impurities, an improved loading of the desired component on the resin and a purer and more concentrated eluate can be obtained by subjecting the resin to a conditioning step after the step of exhaustion of the feed solution onto the resin and before the resin elution step. In the conditioning step, a predetermined isolated quantity of the loaded resin is contracted with a conditioning solution capable of preferentially removing the unwanted impurity component.
