And now, they report that not only is the deposit sufficiently C E L E B R A T I N G YEARS massive in terms of its estimated rare- 50 earth resource supply, but that recovery of service to the ceramic, of said minerals is rather feasible. glass, and petrology The scientists estimate that the amount of rare-earth oxides stashed in the “most communities. promising area” of the widely-distributed supply totals some 1.2 Mt—and that the total supply in the entire area would yield 16 Mt of rare-earth oxides. Just how much is that? According the Scientific Reports paper describing the work, it is enough to “supply these met- als on a semi-infinite basis to the world.” For example, the scientists also esti- mated supply on a per-element basis for some critical rare-earth elements: • 780 years worth of yttrium supply; • 620 years worth of europium supply; • 420 years worth of terbium supply; and • 730 years worth of dysprosium supply. Of course, the presence of the minerals is not enough cause for celebration—but the fact that the scientists’ analysis indi- cates that industrial-scale extraction and purification should be feasible through processing
