in clay minerals. The ores of rare earth elements are mineralogically and chemically complex and commonly radioactive. REE mining is challenging because REEs are concentrated in more than one mineral, and each mineral requires a different costly extraction technology and mineral processing. Therefore, rare earth element deposits in which REEs are largely concentrated in a single mineral .

Deep Sea Mining

Deep Sea Mining

Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost. These issues are much more complied and not as .

 · Many rare earth elements, on the other hand, mostly undergo complex chemical processing to be separated from the ore minerals, and this is in part what makes them so expensive to mine, according to Anzaplan. Once separated, the metals are used to build and improve our modern world. Digging is an inherently dusty process, so it's no surprise that mining kicks up a lot of dust. .

Rare Earth Elements

Geology and Mining. Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner; the concentration of REEs in the Earth's crust is estimated to be between 150 to 220 parts per million, which is higher than the concentration of other metals mined for industrial use, such as Cu or Zn. The concentration of cerium, the most abundant rare ...
