So-called "rare earths," metals with names like Yttrium and Scandium, are not really all that rare. Most are more abundant than silver, gold and platinum. They are found in small concentrations, rather than in large, natural stores. The United States currently imports more than 80% of its rare earth elements from offshore suppliers. A ...

Primary economical deposits of rare-earth elements (REEs) are exhausting all over the world, and it has become necessary to find new sources and methods for their extraction.
Processing of rare earth ores. All rare earth ores contain less than 10 percent of REO and need to be upgraded to about 60 percent for further processing. They are first ground to a powder and then separated from the other materials in the orebody by various standard processes, including magnetic and / or electrostatic separation and flotation.
