American Rare Earths Speeds Up Pilot Plant for Pre-Production Concentrate
Event summary
- American Rare Earths has engaged Jaye T. Pickarts, P.E. to lead its pilot plant program for producing pre-production rare earth concentrate from Halleck Creek ore.
- The company has ordered key processing equipment, including Induced Roll Magnetic Separators (IRMS) from Mineral Technologies and a GradePro Reflux Classifier (RC) from FLSmidth.
- Preliminary test work demonstrated gangue rejection of approximately 94%, TREO recovery of around 70%, and a grade enrichment of roughly ten times relative to feed.
- American Rare Earths has mined approximately 3,100 tonnes of Halleck Creek material to feed the pilot program.
The big picture
American Rare Earths is accelerating its pilot plant program to produce pre-production rare earth concentrate, reinforcing its ambition to become a cornerstone of the emerging U.S. rare earth supply chain. The company's progress is strategically significant as it aims to reduce U.S. reliance on imports and meet the growing demand for rare earth elements essential to defense, advanced technologies, and economic security. The project's scale and the company's commitment to environmentally responsible mining practices further underscore its potential impact on the industry.
