Abstract
The invention relates to a beneficiation process for uranium ores comprising clay and carbonate minerals, the process comprising: performing a hydrocyclone step to obtain a hydrocyclone underflow fraction substantially comprising the uranium component; treating the hydrocyclone underflow fraction to effect a separation of carbonate and uranium minerals; and recovering the uranium-bearing minerals to produce a uranium concentrate.
Claims19
A beneficiation process for uranium ore comprising:
- performing a beneficiation hydrocyclone step to produce an underflow fraction and an overflow fraction according to a size separation parameter, wherein uranium values are in particulate form and predominantly reports to the underflow fraction for further processing, and the overflow fraction contains fine particulate waste material;
- and
- treating the underflow fraction in a separation step to separate carbonate minerals from uranium minerals.
