Rare earth elements (REEs) are a group of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, plus scandium and yttrium. Scandium and yttrium are considered rare earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. Despite their name, most rare earth elements are not particularly rare in the Earth’s crust; however, they are rarely found in concentrated forms, which makes their extraction economically challenging.
The lanthanides are metals that are similar in their properties, including their shininess and reactivity. These elements are key components in a wide range of technological applications due to their unique magnetic, luminescent, and electrochemical properties. They play crucial roles in the manufacture of modern technologies such as smartphones, computers, wind turbines, electric vehicles, and various defense systems. Specific uses include powerful permanent magnets, phosphors in color television and computer screens, catalysts in automotive catalytic converters, and components in rechargeable batteries.
The extraction, refinement, and processing of rare earth elements can be environmentally challenging and technically complex, which has led to concerns about the supply and geopolitical implications of these critical materials. China has been the dominant supplier of rare earth elements, controlling a significant portion of the world’s production and reserves, which has prompted other countries to develop their own REE resources to ensure a stable supply for future technological development.
