Bastnaesite concentrate

TREO content exceeding 62%

Bastnaesite concentrate serves as a foundational source of rare earth elements for advanced material production. With total rare earth oxide (TREO) content exceeding 62%, this high-quality feedstock supports efficient downstream separation and refining, ultimately enabling the creation of high-performance materials for cutting-edge industries.

Chemical composition

Formula: (Ce,La)CO₃F, a rare earth fluorocarbonate mineral.

Typical rare earth distribution (% of TREO): CeO₂ ~49%, La₂O₃ ~34%, Nd₂O₃ ~12%, Pr₆O₁₁ ~4%, Sm₂O₃ ~1%, balance other rare earths. Typical, varies by lot.

Purity: Total rare earth oxide (TREO) content exceeding 62%, composed of greater than 15% neodymium and praseodymium in a 3:1 ratio on a TREO basis.
