Rare earth elements: Where in the world are they?
Most rare earth elements find their uses as catalysts and magnets in traditional and low-carbon technologies.

Cerium the most plentiful REE in the crust, while promethium does not occur naturally and has radioactive isotopes. Global supply chains have long depended on a limited number of countries for mining and processing, prompting continuous diversification efforts and price volatility due to mining, processing, and geopolitical factors. American Molycorp began production at Mountain Pass and targets full capacity to reach 19,050 metric tons, with a separation plant at Mountain for processing. Rare earth elements are found in catalysts and magnets in modern tech, supporting clean-energy applications and advanced manufacturing. These worldwide importance has led to diversification along with supply chain reforms to reduce price swings caused by mining, processing, and geopolitical factors. In sum, rare-earth elements continue to be crucial to modern technology and green energy development.
