    Abstract: The specification discloses a process for stabilising 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 stabilising uranium and thorium.

    Abstract: A process for leaching an ore containing sulphidic copper-containing minerals is disclosed. The process includes carrying out an aerated oxidising leach of a part of the ore and causing reactions with a source of iron such as pyrite in the ore and producing an acidic leach liquor containing ferrous ions, ferric ions, and copper ions in solution. The process also includes carrying out a leach of another part of the ore using the leach liquor produced in step (a) under conditions that minimise reactions with a source of iron such as pyrite in the ore and producing a leach liquor containing copper ions in solution.

    Abstract: The application discloses a process for upgrading a titaniferous material by removal of impurities contained in the material especially radionuclides. The process involves heating the titaniferous material to a temperature of less than 1300° C. to form a solid titaniferous phase and a liquid oxide or glassy phase in the presence of a material that promotes the formations of such phases, cooling the product at a rate that maintains the glassy phase in an amorphous state and leaching the solidified material with an acid or an alkali to remove the impurities. Materials that promote the formation of the desired phases include compounds of alkali metals and boron. Examples include borax, caustic soda, soda ash and silica.
