Ultraviolet lights the way for rare earth recycling

The 17 rare earth elements, widely used in everyday devices from cellphones to magnets and fluorescent lights, aren’t all that rare. They are just finely dispersed in small quantities around the world, making them difficult to mine in substantial quantities. Recycling rare earths is an attractive means to supplement freshly mined stocks, but it remains technically and logistically difficult. Now, a team has developed a more efficient method of recycling two rare earth elements — europium and yttrium — using ultraviolet (UV) light instead of traditional methods involving chemical solvents.

Could U.S. phosphate deposits help meet growing rare earth demand?

The modern world runs on rare earth metals — they are essential ingredients in light bulbs, smartphones, wind turbines and military weapons, among other uses. Currently, China supplies more than 95 percent of the global demand for rare earth elements (REEs), giving it a virtual monopoly. But new research suggests that the United States may contain vast domestic reserves of its own that could dwarf known deposits.

Is there really a minerals crisis?

Reports suggest that the world is running out of crucial supplies of minerals, from copper and lead to the rare earths. But shortages have more to do with sociological and political issues than actual geology.
