Toro Energy Limited (ASX:TOE) advises that Phase 2 of the optimisation studies on the proposed processing circuit at the Wiluna Uranium Project in Western Australia has demonstrated that leaching of beneficiated concentrate occurs relatively rapidly and delivers a high uranium extraction.
The aim of this phase of testwork was to provide an initial estimation of the leach extraction rates and uranium concentration in the leach liquor when beneficiated samples, derived from the prior testwork, were subjected to a carbonate leach circuit. The results show that all concentrates displayed rapid leaching characteristics and high uranium extractions, irrespective of mineralogy.
