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, but the fraction of the heavy rare earths is two to three times larger.
