SOURCE:PHYS.ORGNew technologies and expanding electrification mean a growing need for both common and uncommon metals, such as rare earth metals. One of Europe's largest deposits is in Norra Kärr outside of Gränna.'Norra Kärr can help make the EU self-sufficient in rare earth metals,' says Axel Sjöqvist, author of a new doctoral thesis at the University of Gothenburg.Reliable sources of rare earth metals are required to successfully transition to green energy and for new production of wind turbines and electrical cars. Rare earth metals are used in devices like ...
