Rare-earth element deposits often contain the radioactive elements uranium and thorium, which makes mining, extraction, and waste disposal very hazardous processes. See also: Precious element resources; Radioactive minerals; Rare-earth mining. A number of positive recycling and replacement efforts are in development and operation.
Rare Earth Elements A briefing note by the Geological Society of London Introduction The rare earth elements have long been recognised as useful because of their unusual chemical and physical properties. Their natural occurrence is strongly dependent on geological circumstances, and only in a few locations are they found in sufficient quantity and
The existing recycling infrastructure for fluorescent bulbs makes them good candidates for rare earth recycling, many experts say. Fluorescent light bulbs make use of rare earth elements to fill out the color spectrum: the red and green phosphors in the powder that lines the inside of the lights are the rare earth elements europium and terbium.
"Rare earth elements aren't being recycled from electronics right now, and that's a huge problem — China has a stranglehold on the material supply," Wiens said. "This is a great idea — Apple could single-handedly create a hugely needed market for recycled rare earths." Apple often aims to reuse parts from its old devices.
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.
Rare earth elements are heavier than iron. They are made by supernovae (exploding stars). In nature, fission of uranium-238 creates very small amounts of radioactive promethium. Most promethium is synthetically created in nuclear reactors. Rare earth elements change through time in small quantities (ppm, parts per million).

"This is a great idea — Apple could single-handedly create a hugely needed market for recycled rare earths." Apple often aims to reuse parts from its old devices.
The estimated average concentration of the rare earth elements in the Earth's crust, which ranges from around 150 to 220 parts per million (table 1), exceeds that of many other metals that are mined on an industrial scale, such as copper (55 parts per million) and zinc (70 parts per million).

What Are Rare Earths? Rare earths are a series of chemical elements found in the Earth's crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others.
Rare-earth element - Rare-earth element - Minerals and ores: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the light-atomic-weight elements (i.e., lanthanum, cerium, praseodymium ...
