In a significant development for the rare earth mining sector, Critical Metals Corp has announced the successful replication of its earlier metallurgical tests conducted at the Tanbreez project in Romania. This achievement comes as part of an extensive study reviewed by Professor Tony Tang, an independent consultant whose expertise ensures the reliability of the results. The tests, carried out at Fremantle Metallurgy laboratories, confirm the viability of the initial processes established in the past.
According to the company, the replication of the AMTEC/ALS laboratory results demonstrates a robust foundation for future operations. The incorporation of advanced technologies and methodologies is expected to enhance both the efficiency and profitability of the project, positioning it as a significant player in the global rare earth market.

Breakthrough in metallurgical testing
During the recent tests, the laboratory confirmed the effectiveness of the original process flow sheet established in the past. The team successfully isolated eudialyte, arfvedsonite, and feldspar into high-grade concentrates through a dry magnetic separation method. This method is crucial for the extraction of valuable minerals from the ore.
Implementation of new technologies
Furthermore, the tests incorporated cutting-edge magnetic recovery technologies from a leading supplier. The latest multistage, multi-roller high-intensity permanent rare-earth magnetic circuit demonstrated exceptional performance, operating above 12,000 gauss. This innovative technology not only refined the final concentrate of eudialyte but also produced a secondary mixed concentrate rich in TREEs (Total Rare Earth Elements) that previous technologies could not recover.
The success of these tests is vital for the ongoing development of Critical Metals Corp’s Proof-of-Concept Pilot Plant, which is designed to handle 300 to 500 kg of ore per hour. The plant, with an estimated cost of around $2 million, is projected to be operational in the near future. Integration of the new high-intensity magnetic separation technology is expected to positively impact the project’s economic viability and design.
Strategic joint venture and community engagement
The Tanbreez project operates under a 50:50 joint venture between Critical Metals Corp and Nuclearelectrica Romania. This collaboration aims to optimize the design of the refinery based on early concentrate production from the pilot plant. The initiative is not only a technical endeavor but also a commitment to local communities, as Critical Metals Corp plans to train local operators and mining students in Greenland.
Commitment to sustainable practices
Critical Metals Corp’s approach to mining emphasizes sustainability and local engagement. The company is dedicated to employing and upskilling local personnel as part of its long-term operational strategy. The pilot plant will serve as an educational platform, preparing local communities for future roles within the mining sector. This focus on workforce development aligns with the company’s commitment to responsible mining practices.
The operational scale of the Proof-of-Concept Pilot Plant is designed to generate weekly batches of eudialyte concentrate, which will serve as pre-production material for potential partners. This proactive strategy enables customization of refinery circuits as production ramps up.
Future prospects and market implications
With the successful testing and upcoming pilot plant operations, Critical Metals Corp is well-positioned to become a key supplier of high-grade rare earth concentrates. The anticipated concentrate from the Tanbreez project includes valuable minerals such as Zn, Ga, Rb, Sr, Y, Zr, Nb, La, Ce, and Hf. The market for these elements is robust, with prices varying significantly based on purity and demand, highlighting the strategic importance of this project.
As Critical Metals Corp continues to refine its processes and expand its operations, the Tanbreez project could emerge as a leading source of rare earth elements, catering to both NATO and EU supply chain needs. The company’s commitment to high-purity production—targeting between 99.99% and 99.9995% purity for its rare earth salts and metals—positions it favorably in a competitive market.
In summary, Critical Metals Corp’s ongoing advancements at the Tanbreez project not only underscore its potential for significant contributions to the rare earth sector but also reflect its commitment to sustainable mining practices and community engagement.
