Medallion Resources says it has engaged international engineering group Stantec to evaluate sites in the US for its planned rare earth element (REE) extraction plant.
The plant, which will use feedstock sourced from the southeast US, will leverage Medallion’s proprietary hydrometallurgical process to extract a REE concentrate from by-product monazite sand in a clean, safe, and automated fashion.
Medallion, after many years of test work and development, recently completed the design of this process.
Key features of the enhanced “caustic crack” REE extraction process include:
- Full automation for low manpower requirements and worker isolation from harsh operating environments (chemical, thermal and radiological) for enhanced safety;
- Highly-energy efficient design;
- Option for a zero liquid discharge plant to provide additional flexibility on planning/permitting;
- Waste production options; and
- Employment of only “off-the-shelf” equipment — with innovations on their application.
