A process for separating rare earth ions from thorium ions is described. An aqueous feed solution containing the rare earth, thorium, and phosphate ions is contacted with a strongly acidic cation-exchange resin to remove the rare earth ions from the feed solution. The resin is then separated from the feed solution. The resin is a polymer or copolymer of styrene and contains a sulfonic acid grouping. The rare earths absorbed on the resin are removed by treating the resin with hydrochloric acid which elutes the rare earths in the form of chlorides. Before treating with hydrochloric acid the resin is washed with dilute hydrochloric acid. (N.W.R.)
