Sweden Discovers Hidden Rare Earth Deposits to Reduce China's Grip

Topic: Materials Science

Swedish researchers are exploring their country's mineral resources to produce cleaner rare earth elements and magnets. This could help reduce China's monopoly on these essential materials.

Swedish researchers are working to find a solution to the world's reliance on China for rare earth elements (REE) and powerful magnets made from them. Martin Sahlberg, a Professor of Materials Chemistry at Uppsala University, is leading this effort.

Rare earth magnets are crucial for many modern technologies, including displays and advanced materials. However, their production comes with significant environmental costs. The process often requires toxic chemicals and can harm the environment. China currently dominates the global market for rare earth elements, but Sweden has its own deposits in Kiruna, Bergslagen, and Norra Kärr.

Sahlberg's team aims to create a scientific foundation for extracting these resources domestically while developing new functional magnets. They want to design magnets that match the chemical composition of local deposits, reducing processing needs and environmental impact. This approach could help Sweden lead the green transition and reduce its reliance on China.
