Toro Energy Limited (ASX:TOE) reports that the beneficiation studies on the proposed processing circuit for the Wiluna Uranium Project in Western Australia have successfully demonstrated that a simple screen and de-slime beneficiation circuit process could significantly upgrade the majority of the feed to the proposed mill.
The aim of the beneficiation test work was to identify methodologies to produce a high grade, low mass uranium concentrate as mill feed, thereby delivering greater overall operational efficiencies and reduced costs at Wiluna.
Significantly, the results show that:
- High grade mineralisation associated with fine grained sediments can be beneficiated up to 3.3 times the original grade, resulting in a reduction to 27% of its original mass, with a low 16% loss of the total uranium; and
- The beneficiation upgrades are not grade dependent; they are achieved across all grades from as low as 220 ppm U3O8 to sample grades of more than 2000 ppm U3O8.
