Iondrive Surpasses 90% Rare Earth Extraction in US Testwork, Eyes Modular Scale-Up
Iondrive Limited has confirmed over 90% extraction of key rare earth elements neodymium and praseodymium from US commercial samples, exceeding prior economic assumptions and advancing its modular recycling technology toward commercial deployment.
- US testwork achieves 93.8% neodymium and 95.1% praseodymium extraction
- Results surpass previous techno-economic study assumptions
- Process improvements enhance iron impurity removal and product quality
- Modular, scalable IONSolv™ platform targets US domestic supply chain
- Next steps include product sample production and pre-feasibility studies
High Extraction Rates Validate IONSolv™ Potential
Iondrive Limited (ASX:ION) has hit a significant milestone in its rare earth recycling ambitions, with US-based testwork confirming extraction rates exceeding 90% for neodymium (Nd) and praseodymium (Pr) from commercially sourced magnet feedstocks. The results, delivered by Kingston Process Metallurgy Inc. under ProProcess Engineering’s guidance, showed 93.8% Nd and 95.1% Pr recovery, comfortably surpassing the assumptions underpinning the company’s earlier techno-economic study that forecasted a 46% IRR and US$7 million NPV per modular unit.
This leap in extraction efficiency not only strengthens the commercial case for Iondrive’s IONSolv™ deep eutectic solvent technology but also aligns with the strategic imperative to build domestic rare earth supply chains in the US, a market increasingly focused on reducing reliance on traditional processing centres.
Process Refinements Target Product Quality and Scalability
Beyond raw extraction numbers, the company has made strides in improving impurity management, particularly iron removal, which is critical to producing a saleable rare earth oxide product and minimizing losses. CEO Lewis Utting emphasised the importance of these refinements: "Our focus is now on producing a saleable rare earth product and advancing the process toward commercial deployment." The enhanced iron rejection performance supports downstream process efficiency, a key factor in scaling the technology.
Iondrive is advancing a modular processing model where standalone units can be deployed capital-efficiently across multiple locations, including the US. This modular approach aims to facilitate rapid expansion and aligns with the company’s recent strategic pivot toward commercialisation under Utting’s leadership, following his appointment earlier this year to drive scale-up efforts.
Next Steps Toward Commercial Readiness
In the coming quarter, Iondrive plans to finalise its Phase 2 program, focusing on further optimisation of processing conditions, iron rejection, and scale-up parameters. The company will also produce mixed rare earth oxide samples to engage potential customers and strategic partners, and develop advanced engineering and commercial plans for modular deployment tailored to the US market.
These developments follow Iondrive’s recent progress in securing US funding and commissioning pilot plants, which marked a shift from development to commercialisation of IONSolv™ technology. The company’s push to validate its technology with commercial-grade feedstocks and its modular strategy reflects an ambition to capture a foothold in the growing US rare earth recycling sector, which is underpinned by government interest in securing critical mineral supply chains. The current testwork success builds on earlier achievements such as 85% silver extraction in solar panel recycling, highlighting the versatility of IONSolv™ across different materials.
While promising, these results remain a step in a longer journey toward full commercial deployment. The timing and scale of modular plant rollouts, customer offtake agreements, and potential US government grant support will be critical to watch as Iondrive transitions from technology validation to market execution.
Bottom Line?
Iondrive’s >90% extraction rates mark a key technical milestone, but commercial success hinges on scaling modular plants and securing strategic partnerships in the US rare earth market.
Questions in the middle?
- How quickly can Iondrive scale its modular processing units across multiple US locations?
- Will the company secure offtake agreements or government grants to underpin commercial deployment?
- How will ongoing iron impurity management affect final product quality and market acceptance?
