Macusani Yellowcake Inc. (TSXV:YEL,FWB:QG1) reported that preliminary results from tests conducted on four leach solutions demonstrate applicability of the ion exchange technology for the uranium recovery from Macusani leach solutions.
Two resin types exhibited high uranium removal characteristics in single stage tests. Resin type I achieved removal efficiencies of 76 to 96.5% while resin type II achieved removal efficiencies of 65 to 93.0%. In two stage tests, uranium removal efficiency reached was in excess of 99.6% for resin type I.
Macusani Yellowcake President and CEO Dr. Laurence Stefan said:
The recent ion exchange tests have found a suitable ion exchange resin capable of achieving above 99% removal of uranium from pregnant leach solutions. The results demonstrate the excellent applicability of the ion exchange technology for the uranium recovery from Macusani leach solutions. The use of ion exchange instead of solvent extraction, for the first stage of uranium recovery from leach solution, on the Macusani plateau has the advantages of reduced organic solvent losses through evaporation and reduced solvent extraction waste stream production. These advantages are positive both financially and environmentally.
