A project that aims to identify Central Appalachian sources of rare earth elements and critical minerals has received $500,000 in federal funding to continue for another six months.
The 17 rare earth elements — so called not because they’re uncommon, per se, but because they typically occur in such low concentrations that easily extracted deposits are rare — include scandium, yttrium and a group of 15 elements collectively called the lanthanides. The 50 critical minerals identified as such by the U.S. Geological Survey are considered essential to the economy and have no viable substitutes; they include aluminum, cobalt, graphite, lithium, nickel and nearly all of the rare earth elements.
