The radionuclide $$^{67}$$Cu was produced via the $$^{68}$$Zn(p,2p) $$^{67}$$Cu reaction by irradiating enriched $$^{68}$$Zn targets with 70-MeV proton beam. $$^{67}$$Cu was chemically separated from target zinc material by an ion-exchange chromatography method using Chelex-100 chelating ion-exchange resin. Procedure for recovery of the enriched $$^{68}$$Zn was developed. The target recovery yield in this method was evaluated to be more than 97%.
