Jan 11, 2012· Rare earth mining pollution is an unfortunate side effect to the ever growing mining industry's desire to obtain and control the worldwide supply of these lanthanide and actinide elements which happen to be not so rare after all.
Nov 20, 2002· Rare Earth Element Abundances "Rare" earth elements is a historical misnomer; persistence of the term reflects unfamiliarity rather than true rarity. The more abundant REE are each similar in crustal concentration to commonplace industrial metals such as chromium, nickel, copper, zinc, molybdenum, tin, tungsten, or lead (fig. 4).
White Paper on Separation of Rare Earth Elements, February 20, 2016. 6 the enormous amounts of energy and water required to mine and process ore to recover desired metals, since ore grade is, usually, 1 .
Seventeen elements form the group known as the Rare Earth Elements (REEs): the 15 lanthanides, yttrium, and usually scandium. Current uses include catalytic converters, computers, cell phones, hightemperature magnets, batteries for hybrid and electric vehicles, medical devices, and military applications such as missiles, jet engines, and satellites.
Today's rare earth production is centered mainly in China, where lax oversight raises concerns about high levels of pollution from mishandling of the toxic waste produced during mining and processing, as well as child labor exploitation.
Nov 18, 2013· A shortage of "rare earth" metals, used in everything from electric car batteries to solar panels to wind turbines, is hampering the growth of renewable energy technologies. Researchers are now working to find alternatives to these critical elements or better ways to recycle them.
Apr 13, 2018· Japanese researchers estimate the roughly 2499squarekilometer region of seabed holds more than 16 million tons of rare earth oxides, including 780 years' worth of the global supply of yttrium, 620 years' worth of europium, 420 years' worth of terbium, and 730 years' worth of dysprosium, they write this week in Scientific Reports.
