Source:The term “rare earth element” has a specific meaning to scientists. Most people focus on the word “rare” and assume it means the 17 so-called rare earth elements are just that — rare. In fact, some of them are more abundant than copper. What makes them rare often has more to do with the relatively few places around the world where they can be found and the difficulty of separating them from other elements in commercially viable quantities. In today’s world, political considerations can also impact the availability of rare earth elements.For instance, much of the ...

This demand, equivalent to that of about 20 million...
