  • Processing Is Key Element in US Rare-Earth Woes,

    China controls 95 percent of the world's rare-earth supply. The key to this monopoly isn't an abundance of rare-earth deposits, but its expertise in processing ore into oxides and pure metal. TheRare-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.
