RARE EARTH ELEMENTS: A REVIEW OF PRODUCTION,

Dec 08, 2015  Rare earth elements (REEs) are a group of 15 chemical elements in the periodic table, specifically the lanthanides. Two other elements, scandium and yttrium, have a similar physiochemistry to the lanthanides, are commonly found in the same mineral assemblages, and are often referred to as REEs. REEs have not been mined in the United States for about 20 years, and prior to that time, the
