Queensland critical minerals lab: design and testwork gains for process engineers
Reviewed by Joe Ashwell

30 Second Briefing
A new state-of-the-art minerals processing facility has opened in Queensland to accelerate testwork and flowsheet development for critical minerals, positioning local projects to move faster from resource definition to pilot scale. The lab is geared to handle complex ore characterisation, bench-scale processing and variability testing, supporting commodities such as rare earths, vanadium and battery-grade manganese under controlled, repeatable conditions. For miners and process engineers, this centralised capability should de-risk plant design, reduce reliance on overseas laboratories and shorten timelines for metallurgical optimisation.
Technical Brief
- Facility is configured as a dedicated minerals processing lab rather than a mine-site pilot plant.
- Located in Queensland, giving proximity to emerging critical minerals hubs in the state’s north and west.
- Centralised testwork capability reduces logistics complexity for sample export to overseas laboratories and associated delays.
- Co-location of testing, innovation and research functions enables tighter feedback loops between geometallurgy and flowsheet design.
- Likely to support both greenfield and brownfield projects needing bench-scale verification of novel processing routes.
- Shared infrastructure model should lower per‑project metallurgical test costs compared with standalone bespoke facilities.
- For similar critical minerals clusters, such hubs can anchor regional supply chains and skills development.
Our Take
Critical minerals pieces in our database often centre on mine approvals or downstream processing plants, so a Queensland state-of-the-art minerals processing facility signals a push to de‑risk flowsheet development earlier in the value chain.
Within the 1065 Mining stories, Australia frequently appears in critical minerals coverage as a low‑sovereign‑risk jurisdiction, meaning a Queensland lab of this type is likely to become a preferred test hub for international juniors needing bankable metallurgical data.
For Queensland specifically, where several critical minerals projects are still at scoping or PFS stage in our coverage, access to a dedicated processing facility can shorten metallurgical testwork timelines and help projects move from concept to financing more quickly.
