  • What are Rare Earth Elements?

    Through a process of crushing, milling, conditioning, and flotation, rare earth elements are separated from waste to produce a mixed rare earth concentrate. The mixed rare earth concentrate undergoes a complex chemical process to purify, recover, separate, and precipitate individual rare earth elements.
