Rare earth elements used to appear fairly close to the surface of the Earth, but humans have increasingly mined out accessible areas. As REEs become harder to extract, there is even discussion about mining them from the ocean floor. But for now, REEs come from open pit mines.

Over the past decades there has been an explosion in the demand of rare earth metals, as more and more devices requiring rare earth metals rise. Devices such as computer memory, rechargeable batteries, magnet, and even defense equipment/devices such as night vision goggles, precision guided weapons and GPS equipment require rare earth metals. Companies mining and refining rare earth metals are profiting from the decades long increase in demand of these metals.
The rare earths, or rare earth elements , are a relatively abundant group of elements consisting of scandium, yttrium, and the 15 elements of the lanthanide series of the periodic table. Scandium is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely occurs in concentrated quantities because it does not combine into common ores or minerals.
The Pentagon also signed DPA Title III agreements with TDA Magnetics of Rancho Dominguez, California, and Urban Mining Co. of San Marcos, Texas, for rare earth element magnet supply chain studies and inventory demonstrations. The funding was $2.3 million and $860,000, respectively.
If approved, it would let mining companies deduct the costs of building rare earth mines, processing facilities, and equipment purchases from their tax bills. And their customers would be able to ...
