Rare-earth mineral security?

• Retric 10y ago
  Rare-earth means low concentrations. There is still a lot of this stuff in the darts crust an it's not destroyed with use.

  Rare-earth minerals aren't actually rare. The name comes from the relatively low concentrations in which you find them naturally. But we won't run out; they're just more expensive to refine as we tap lower concentration sources. Even poor sources are going to yeild minerals at a cost that's a few orders of magnitude less than a what you'd get on the moon.
