Rare Earth Elements (e.g., Neodymium, Dysprosium)
Rare earth elements (REEs) are a group of 17 metallic elements, including the 15 lanthanides plus scandium and yttrium. These elements are critical in modern technology due to their unique chemical and physical properties. Among the most notable REEs are neodymium and dysprosium, which are essential for high-performance magnets, electronics, and clean energy solutions.
