Australian Vanadium Limited announced the production of ultra-high purity vanadium pentoxide at greater than 99.9 per cent purity on a pilot scale. This significant milestone, achieved using AVL ore, validates a processing route that can be seamlessly integrated into AVL’s existing flowsheet.
The technology employed is well-established and can be readily scaled to meet the growing demand for ultra-high purity vanadium products, particularly in critical sectors such as the chemical and aerospace industries.
“AVL’s ability to produce 99.9% ultra-high purity vanadium pentoxide, in addition to our 99.5% standard high purity vanadium pentoxide, allows us to further strengthen our competitive advantage in specialised markets in which premium products attract a higher value,” said CEO Graham Arvidson.
Arvidson also acknowledged the collaborative efforts with the Australian Nuclear Science and Technology Organisation and the support received from the Australian Government.
He highlighted the significance of value-added processing in Australia, aligning with the Federal Government’s Critical Minerals Strategy 2023-2030 and contributing to the nation’s transition to a net-zero future.
The achievement of ultra-high purity vanadium pentoxide was partly made possible by a $3.69 million grant from the Australian Government’s Modern Manufacturing Initiative Translation grant under the National Manufacturing Priority Roadmap.
AVL collaborated with ANSTO to develop a viable processing route, culminating in the successful operation of the pilot plant.
The pilot plant’s feed materials were generated during AVL’s pilot beneficiation, pyrometallurgy, and hydrometallurgy programs conducted as part of the Bankable Feasibility Study in 2021.
Comprehensive testing and analysis confirmed the ultra-high purity of the vanadium pentoxide product, with the most significant impurity, chromium, reduced to minimal levels.
