ABSTRACT:
A process for selectively removing tetravalent and/or hexavalent uranium ions from a solution by using a chelate-forming cation exchanger. The solution may be prepared by contacting uranium bearing ore with either an acid or a dilute carbonate or bicarbonate solution. To facilitate removal of the uranium ions, the solution may have a pH value greater than 1.0 and a redox potential of from -50 to +250 mV.
