REEs, or Rare Earth Elements, are a group of 17 chemically similar metallic elements found in the Earth’s crust. They aren’t actually “rare” in terms of how much exists, but they are rarely found in concentrated amounts, which makes mining and extracting them difficult.
REEs are sometimes called the “vitamins of modern technology” because they are needed in small amounts, but are essential for many popular products, including:
Electronics – smartphones, computers, TVs, LED lights, headphones
Green technology – wind turbines, electric vehicles, solar panels, rechargeable batteries
Military & Aerospace – jet engines, lasers, radar
