While identification in polymetallic ore can be difficult, processing these materials can present extra challenges. Removing and purifying the rare earths from their native ore (less than 10% combined rare-earth ore) into useable material (greater than 60% rare-earth ore) can usually be done by magnetic, electrostatic, or gravimetric processes.

The REs are a family of 17 metallic elements formed by the group III (Sc, Y) and the lanthanide series (La–Lu). The name "rare earth" is misleading and does not represent a geological scarcity ().The origin of this description lies in the occurrence of REs as a mixture of elements in minerals, generally at low concentration.
