rare-earth element - Processing ores | Britannica

rare-earth element - rare-earth element - Processing ores: All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.

The Geology of Rare Earth Elements

Rare earth elements, on the other hand, are typically extracted and refined through dozens of chemical processes to separate the different rare earth elements and remove impurities. The principal deleterious impurity in REE-bearing minerals is thorium, which imparts an unwanted radioactivity to the ores.
