What are Rare Earth Metals?
Rare earth metals, also known as rare earth elements (REEs), are a group of 17 chemically similar metallic elements: the 15 lanthanides plus scandium and yttrium. Despite their name, they are not exceptionally rare in the Earth’s crust, but they are rarely found in concentrations economically viable to mine. They are crucial components in a vast array of modern technologies, including consumer electronics, defense systems, renewable energy technologies (like wind turbines and electric vehicles), and medical devices. Their unique magnetic, catalytic, and electrical properties make them indispensable for high-tech applications.
Examples of REEs include Neodymium (Nd) and Praseodymium (Pr), essential for powerful permanent magnets used in electric motors and wind turbines; Dysprosium (Dy) and Terbium (Tb), which enhance the performance of magnets at high temperatures; Cerium (Ce), used in catalysts and polishing compounds; and Europium (Eu) and Terbium (Tb), vital for phosphors in lighting and displays. The strategic importance of REEs has placed their supply chains under intense global scrutiny, particularly given the concentration of mining and processing in specific regions. In 2026, securing a stable and diverse supply of REEs is a global priority.
The Strategic Importance of Rare Earths
The strategic importance of rare earth metals cannot be overstated in the context of modern economies and national security. Their unique properties enable advancements in critical sectors such as defense, aerospace, telecommunications, and green energy. For example, REEs are vital for the production of high-performance magnets used in jet fighters, missile guidance systems, and advanced radar. In the renewable energy sector, they are essential for the magnets in wind turbines and the batteries used in electric vehicles.
The concentration of global rare earth supply, particularly mining and processing, in a few countries has led to concerns about supply chain vulnerability and geopolitical risks. This has prompted many nations, including the United States, to focus on diversifying supply sources, developing domestic processing capabilities, and investing in recycling technologies. Ensuring a stable and secure supply of REEs is therefore a key strategic objective for many governments and industries worldwide, a focus that will only intensify through 2026.
Rio Tinto’s Involvement in Rare Earths
Rio Tinto is a significant player in the global mining industry, and its involvement in rare earth elements is notable, particularly through its operations in the United States.
