Rare Earth Elements

Rare Earth Elements (REE) are a group of 17 metals made up of 15 lanthanides, plus scandium and yttrium. At the Copi Project the rare earths bearing minerals are found in the form of monazite and xenotime grains. Monazite is a primarily reddish‐brown phosphate mineral that contains REE and thorium. Xenotime is a rare‐earth phosphate mineral, the major component of which is yttrium orthophosphate.

REE are necessary components for a wide range of applications, especially high‐tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flatscreen monitors and televisions. The global demand for REE has increased significantly in line with their expansion into high‐end technological, environmental and economic environments.
