DFS pilot test results verify multiple positive outcomes for crushing, milling and beneficiation circuit (CMB) design for The Australian Vanadium Project in Western Australia.
- Rigorous pilot-scale test work has validated an optimised beneficiation flowsheet.
- Test work focused on processing of two likely ore feed blends, representative of the average life-of-mine and the first five years of forecast process feed.
- Findings confirm the Project’s high vanadium recoveries and consistent excellent concentrate qualities.
- Concentrate generated from life-of-mine average feed blend achieved 76% vanadium recovery, at a grade of 1.37% V2O5 and 1.68% SiO2.
- Year 0-5 pilot testing achieved 69% vanadium recovery to concentrate at 1.39% V2O5 and 1.83% SiO2.
- High vanadium recovery and low silica content represent unique value opportunities for AVL in ongoing economic studies.
- Pilot work for roasting; water leaching and high purity vanadium extraction underway with partners Metso, ALS and ANSTO to define final processing circuit design for the Project.
- AVL’s rigorous approach to test work significantly reduces future risk, by ensuring the process will work as intended when built at full scale, increasing attractiveness to potential Project investors.
