The Rare Earth Elements: An Introduction Apr 2026

Chemically, REEs are known for their similar ionic radii and oxidation states (usually +3), which causes them to occur together in mineral deposits. This similarity makes the chemical separation of individual elements a complex and energy-intensive process. 2. Critical Applications

The REE market is characterized by high geographical concentration. For decades, China has dominated the global supply chain, controlling a vast majority of both mining and processing capacity. This has raised significant economic and national security concerns for other nations, leading to a global push to diversify sources, reopen mines (like Mountain Pass in the U.S.), and invest in recycling technologies. 4.

These same magnets are vital for the generators in wind turbines and the motors of electric vehicles (EVs). Chemically, REEs are known for their similar ionic
