Abstract:
Described herein are technologies for concentrating rare-earth elements from a heavy fraction of grit in gangue produced in kaolin mining. In some examples, grit is separated as a non-clay fraction of gangue produced in a kaolin mining operation. The grit is separated into a heavy mineral grit sub-fraction and a light mineral grit sub-fraction. Rare-earth elements, particularly heavy rare-earth elements, are thereafter extracted from the heavy mineral grit sub-fraction using various extraction technologies.

Claim (Index 11):
The method of  claim 10 , wherein the rare-earth element comprises cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb) or yttrium (Y).
