• China, the world’s top processor of rare earths, banned the export of technology to extract and separate the critical materials on Thursday, the country’s latest step to protect its dominance over several strategic metals.
• Rare earths are a group of 17 metals used to make magnets that turn power into motion for use in electric vehicles, wind turbines and electronics.
• While Western countries are trying to launch their own rare earth processing operations, the ban is expected to have the biggest impact in so-called “heavy rare earths,” used in EV motors, medical devices and weaponry, where China has a virtual monopoly on refining.
