Conclusions

  1. (1)

    Uranium is separated from thorium and rare earths from solutions containing as little as 0·45 g. U3O8/litre and U3O8/ThO2+Rare earth oxides =0.·1 if the pH of the solution before adding KF or NH4F is about 3, or less.

  2. (2)

    Uranium is separated from iron in the pH range of 6 to 6·5 in solutions containing 0·45 g. U3O8/litre and U3O8/Fe2O3=1·0.

  3. (3)

    Complete separation of iron from uranium is achieved only after washing the peroxy complex of uranium with a large volume of water.

Fuller details of the method will be published elsewhere.
