Abstract: PCT No. PCT/AU93/00413 Sec. 371 Date Apr. 10, 1995 Sec. 102(e) Date Apr. 10, 1995 PCT Filed Aug. 13, 1993 PCT Pub. No. WO94/05015 PCT Pub. Date Mar. 3, 1994The specification discloses a process for stabilizing radionuclides extracted during the upgrading of minerals. The process comprises forming a composition of a radionuclide and a component and roasting the composition so that the component forms a crystalline phase having a structure that binds the radionuclides. Suitable components include a compound of a lanthanide and/or phosphorus and zirconia. Zirconia in its cubic form is useful in stabilizing uranium and thorium.
