US reserves of rare earth elements assessed for first time
The US has 13 million tonnes of rare earth elements but it would take
years to extract them, suggests the first detailed report on the country's supply. "Rare earth" is an alternative name for the lanthanides – elements 57 to 71 – plus yttrium and scandium. China controls 97 per cent of the world's supply and has been tightening its export quotas, sparking concerns that the rare earths could live up to their name. See a map of other rare earth sites in the US. http://t.co/le90e2O The report suggests the US might break its dependency on China's rare earth monopoly by looking to other future suppliers of rare earths, including Australia and Canada. http://t.co/le90e2O |
