Key Highlights:
- Successful Conversion Testwork – Produced ferroniobium with 65.7% niobium and 24.3% iron.
- Proof-of-Concept Complete – Final stage of a conventional ferroniobium flowsheet successfully demonstrated.
- Major Market Opportunity – Ferroniobium accounts for 90% of global niobium consumption.
- Strong Metallurgical Performance – Initial 84% niobium recovery, exceeding expectations.
- Ongoing Testwork – Further studies to optimise niobium product development and processing efficiencies.
Milestone Achievement for WA1
WA1 Resources Ltd (ASX: WA1) has achieved a major milestone by successfully producing ferroniobium from refined concentrate at its 100%-owned West Arunta Project in Western Australia. This marks a significant step in demonstrating the commercial viability of niobium extraction from Luni.
Managing Director Paul Savich hailed the achievement, stating:
“To have progressed from our first testwork to ferroniobium production in just over a year is an incredible achievement. The results confirm Luni’s suitability for a conventional ferroniobium flowsheet, and we’re now expanding testwork to explore other high-value niobium products.”
Ferroniobium and the Global Market
Ferroniobium is primarily used in high-strength, low-alloy (HSLA) steels, with global demand exceeding 125,000 tonnes per annum. WA1’s success in producing ferroniobium underscores the potential for Luni to become a key future supplier.
Conversion Testwork – How It Works
The testwork followed a conventional aluminothermic reaction process, where refined niobium concentrate was blended with iron oxide, aluminium, and fluxing agents. The reaction successfully removed impurities, producing a ferroniobium product within commercial-grade specifications.
- First-pass niobium recovery of 84% – Expected to improve with further optimisation.
- Future testwork will refine the iron and aluminium mixture to meet typical commercial ferroniobium standards.
Next Steps for WA1
WA1 continues to advance metallurgical testwork, focusing on:
- Optimising beneficiation – Expanding flotation testing and assessing mineral variability.
- Refining and conversion improvements – Enhancing ferroniobium purity and exploring high-value niobium oxides for superalloy and battery markets.
- Defining a broader resource envelope – Beneficiation testwork on samples from a wider area of Luni.
With ferroniobium production now proven, WA1 is well-positioned to capitalise on growing global demand for niobium and advance towards potential development.
