· rareearth element rareearth element Processing ores: All rareearth 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.
Rare earth element ores tend to contain a range of different metals in their structure, including aluminum, arsenic, barium, beryllium, cadmium, cobalt, copper, lead, manganese, and zinc. These are the most harmful metals that are found in rare earth mines, and are separated from the ores during the refining process, as well as allowed into the open air in mines.
