2020-1-15  physical beneficiation process developed by Marenica Energy, Australia (patent pending), for upgrading low grade surficial uranium deposits typically containing carbonates, clay minerals, and often sulphates. It involves the sequential removal of gangue minerals by commonly used unit operations to achieve a comparatively high grade concentrate without the use of chemicals. The initial step typically comprises wet scrubbing and screening to separate into fine and coarse fractions. The undersize fraction contains most of the uranium as an intermediate concentrate which may be further processed in a secondary beneficiation stage to produce a high grade uranium concentrate. Possible methods for secondary beneficiation

U-pgrade™

The U-pgrade™ process is a physical beneficiation process. As a result of up to 50 times physical reduction in ore mass, use of chemicals in the leach process are significantly reduced. This reduction results in reagent consumption of less than 5% compared to conventional processes, thus there is far less impact on the environment.
