SEPARATION OF THORIUM FROM LANTHANONS
A process for the separation of a thorium salt from an aqueous feed solution contalning thorium, lanthanon, nitrate, and phosphate ions, in which the feed solution is extracted with an organic solvent immiscible with water, the process being performed in the presence of ferric ions, is described. Aluminum ions may be used instead of ferric ions. The ferric ions are at least 0.89 g greater than for each gram of phosphate ions present in the feed solution. If ferric nitrate is used for adding the ferric ions then at least 7 g must be added for each gram of phosphate ions. For aluminum, the ions must be 0.5 g over each gram of phosphate ion. Tributyl phosphate is used for the organic solvent in admixture with a xylene. The feed solution is free from sulfate and chloride ions, and the solution contains from 2 to 8 molar of nitric acid, preferably 3 to 4 molar. (N.W.R.)
