Nuclear Rare Metals and their Separation in Advanced ORIENT Cycle Strategy

New concept of nuclear rare metals was proposed. Hydrometallurgical separationsof such nuclear rare metalshavebeen progressed in the frame of strategic Advanced (Adv.-) ORIENT Cycle research in Japan. A hybrid separation system byion exchange chromatography(IXC)and catalytic electrolytic extraction (CEE) will meetwell with the concept of Green Chemistry, thereby being proposed as a vitalseparation tool forlight PGM(Ru, Rh, Pd), Tc and f-elements. Adv.-ORIENT Cycle process cannot only improve the rad. waste problem, but also offer usefulrare metals to theleadingindustries as for the second resource.
