By monopolizing the mining of rare-earth metals, China could dictate the future of high-tech.
Most people have no idea what’s in an iPhone. Yttrium and praseodymium don’t exactly roll off the tongue, but they’re part of what make smartphones so small, powerful, and bright. These exotic materials are among the planet’s 17 rare-earth elements, and surprisingly, the soft, silvery metals are not at all rare.
But they’re found in tiny concentrations, all mixed together, and usually embedded in hard rock, which makes them difficult — and messy — to isolate. In China, which mines 89 percent of global output, toxic wastes from rare-earth facilities have poisoned water, ruined farmlands, and made people sick.
Beyond high-tech gadgets, rare earths play a critical role in national defense, enabling radar systems and guided missiles. Ironically, they also power clean-energy technologies, such as wind turbines and electric cars.
