The Rare Earth Elements: An Introduction < 2025-2026 >

REEs are critical in precision-guided munitions, sonar, and laser range-finding.

Neodymium and praseodymium are used to create the world’s strongest permanent magnets, found in everything from smartphone speakers to hard drives. The Rare Earth Elements: An Introduction

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. Environmental Impact REEs are critical in precision-guided munitions, sonar, and

The Rare Earth Elements: An Introduction are a set of seventeen metallic elements, including the fifteen lanthanides on the periodic table plus scandium and yttrium. Despite their name, they are relatively abundant in the Earth’s crust; however, they are rarely found in concentrated, economically exploitable deposits, making their extraction and refinement uniquely challenging. 1. Classification and Chemical Nature The REEs are divided into two main categories: For decades, China has dominated the global supply

REEs are the "vitamins" of modern industry—required in small amounts but essential for performance.
