Laterite clays are a commercial source of the heavy lanthanides and yttrium. Other minerals that have been used as a source of rare earths are apatite, euxenite, gadolinite, and xenotime. Allanite, fluorite, perovskite, sphene, and zircon have the potential to be future sources of rare earths. (In addition, uranium and iron tailings have been ...

Rare earth elements (REE) include the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. All these metals occur together in different types of REE deposits such as carbonatites, alkali syenites and monaziterich placers, and are found in more than 250 minerals in the Earth's crust. The future of the world's green …
