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 10):
The method of  claim 1 , wherein concentrating the rare-earth element from the heavy mineral grit sub-fraction comprises performing a thermal treatment of the heavy mineral grit sub-fraction or acid baking of the heavy mineral grit sub-fraction.
