As the demand for rare earth elements increases world-wide, so too do the mining activities associated with rare earth element extraction. Rare earth elements are listed as 15 elements on the periodic table constituting what is known as the lanthanide series, ranging in atomic number from 57 (lanthanum) to 71 (lutetium), as well as scandium (Sc) and yttrium (Y), which serve as essential inputs for information and energy technologies, especially renewable energy technologies.
