G21 (21) u201004276 ============= epaa, epaexaThe radioactive and rare-earth element separation method from flotation benefication wastes and coal mining and mineral ore involves solubilization, mixing, separation of hard fraction from liquid, settling-down and gravity sedimentation. After flotation benefication the wastes are processed with calcimine for precipitation and sedimentation of uranyl insoluble compounds and separation them from mother solution, then they are treated with orthophosphoric acid with content to 5% of HF mother solution up to creation of insoluble phosphates and rare-earth element fluorides with the following separation them by means of sedimentation.
