In summary the work to date indicates that the main highvalue rare earth minerals are Dark Monazite, enriched in Neodymium, Europium, and Xenotime (an Yttrium Phosphate mineral).
Rare Earths. Rare Earths include the unique elemental suite known as the Rare Earths Elements (REE's) and a select group of specialty metals produced primarily for technology applications. At Ucore, our focus is on Heavy REE's (a class of REE's known for their high value relative to other REE's) and collateral metals often found in concert with REE deposits.
Rare Earths in the United States. Ucore owns multiple properties across North America, but its primary asset is its 100percentowned BokanDotson Ridge Project in Alaska. According to the company website, this property is rich in heavy rare earth elements, such as dysprosium, terbium and yttrium.
Dec 23, 2011· Definition of Rare Earth Element. Rare earth elements can be found in a variety of minerals, but the most abundant rare earth elements are found primarily in bastnaesite and monazite. Bastnaesite typically contains light rare earths and a small amount of the heavies, while monazite also contains mostly the light,...
