The issue would be that the processes used to extract it have develop into too costly, troublesome or harmful to make mining worthwhile. Opening an expensive mine to extract a mineral no one wants just does not make sense - it can be like constructing a manufacturing unit that only manufactures LaserDisc players and telegraph elements.

For a still-standing instance of a walled metropolis, check out the picturesque Quebec City in jap Canada. Some are abundant sufficient that we do not have to worry about running out anytime soon. Greenland had the final cryolite deposits rich sufficient to make extraction worthwhile, but the mine closed in the 1980s when new processing methods let us make aluminum with out it. Because the 1980s, a lot of the world has been content to let China take care of ninety five % of rare earth mining. Don't let the label fool you: They're not hard to find.
