Searching For Alternatives To China's Rare Earth Monopoly

KantIsDead writes "MIT's Technology Review adds to the ongoing discussion of China's monopoly on rare earth metals, an issue that was temporarily catapulted to national attention during China's rare earth embargo of Japan. The current article focuses on the search for alternatives to rare earth metals that would undercut China's monopoly and allow nations to develop their industry without fearing the hand of a Chinese embargo. From the article: 'In the US, the Chinese dominance of rare-earth mineral production has prompted a surge of funding focused on developing permanent magnets that use less, if any, rare-earth materials, such as nearly $7 million from the Advanced Research Projects Agency for Energy (ARPA-E). In one of these projects, University of Nebraska researchers are working to enhance permanent magnets made with an alloy iron and cobalt, or FeCo. This class of materials is sold today, but delivers half or less of the power of the best rare-earth-based magnets. The Nebraska researchers will focus on ways to dope the structural matrix of these alloys with traces of other elements, thereby rearranging their molecular geometry to create stronger, more durable permanent magnetic materials.'"

  1. China is just the cheapest producer like Saudi by Anonymous Coward · · Score: 5, Informative

    There are lots of rare earths in other countries. China is just the cheapest place to extract it. If the price goes up then other deposits will be able to be brought online economically.

  2. Chorus Motors electric motors dont use rare earths by Anonymous Coward · · Score: 4, Informative

    Chorus Motors is working with Boeing to put their electric wheel motors in Boeing's new aircraft. They are powered by the plane's APU instead of using the engines.

    Their technology results in a smaller motor with higher torque that does not require an assist from an ICE at higher speeds in an electric vehicle. It also does not use any rare earths.

    Molycorp is restarting the rare earths mine in the U.S. but the industry to process the ore will take 15 years to redevelop.

    "While U.S. deposits also exist in several states such as Idaho, Wyoming and Utah, they are still being explored and could take as many as 15 years before becoming fully operational, according the GAO report."

  3. Rare earth is not rare... by mathfeel · · Score: 5, Informative

    There were many mines in North America. They were shut down because to comply with US/Canadian environmental regulation and pay the wages here would put them in a huge competitive disadvantage versus the Chinese mines. You just can't compete with places where they put environment and worker protection at such low places in their priorities.
