Proposed ban by China of rare-earth metal exports would affect hybrid cars, CFLs
China’s Ministry of Industry and Information Technology is proposing a total ban on exports of terbium, dysprosium, yttrium, thulium, and lutetium. Other metals such as neodymium, europium, cerium, and lanthanum would be restricted to a total of 35,000 tonnes a year, which is far below global needs. Many of these are vital to energy-efficient technology: Neodymium is used in rare-earth magnets for high-efficiency motors: Chances are your new front-loading clothes washer uses rare-earth magnets in its motor. From the Telegram’s article: “No replacement has been found for neodymium that enhances the power of magnets at high heat and is crucial for hard-disk drives, wind turbines, and the electric motors of hybrid cars. Each Toyota Prius uses 25 pounds of rare earth elements. Cerium and lanthanum are used in catalytic converters for diesel engines.”
Terbium is used in the phosphors of compact fluorescent lights (CFLs.) It’s not an essential ingredient apparently, but used to tweak the CFL’s light to a more pleasant spectrum.
Some of these metals are currently produced only in China, so if China restricts or bans their exports it will affect energy-efficient products worldwide. According to the article, China’s intent is not to hold the rest of the world ransom – China needs these metals for its internal consumption.
Anybody remember the rush to discover uranium deposits in the 50s and 60s? Geiger counters are a running joke in cartoons of that era. We may be heading into a hunt new non-Chinese deposits of rare-earth metals.
The Telegram article also says China had put global competitors out of business in the early 1990s by flooding the market, leading to the closure of the biggest US rare earth mine at Mountain Pass in California - now being revived by Molycorp Minerals. From the Molycorp website: “Fortunately, the U.S. has one of the world’s largest and richest Rare Earth deposits at Molycorp Minerals’ facility in Mountain Pass, California. At Mountain Pass we are producing a variety of Green Elements and plans are in place to bring the facility back into full production. With appropriate federal assistance for research, development and capital costs, Molycorp Minerals is prepared to move forward to reestablish domestic manufacturing capacity on an expedited basis.”
