- Enough rare earth minerals have been found off Japan to last centuries
- Rare earths are important materials for green technology, as well as medicine and manufacturing
- Where would we be without all of our rare-earth magnets?
Rare earth elements are a set of 17 metals that are integral to our modern lifestyle and efforts to produce ever-greener technologies. The “rare” designation is a bit of a misnomer: It’s not that they’re not plentiful, but rather that they’re found in small concentrations, and are especially difficult to successfully extract since they blend in with and resemble other minerals in the ground. China currently produces over 90% of the world’s supply of rare metals, with seven other countries mining the rest. So though they’re not precisely “rare,” they are scarce. In 2010, the U.S. Department of energy issued a report that warned of a critical shortage of five of the elements. Now, however, Japan has found a massive deposit of rare earths sufficient to supply the world’s needs for hundred of years. […]
