This project is no longer open for submissions. Overview: We are seeking to either drastically reduce the heavy rare-earths (HRE) in high-temperature permanent magnets (e.g. Nd-Fe-B) or to totally replace rare-earth magnets by other means, while maintaining .
Sep 18, 2019· Apple Inc's new iPhones will used recycled rare earth elements in a key component, the company said on Wednesday. Apple said it will used recycled rare earths in its "Taptic Engine," a part that lets iPhones mimic a physical button click despite being a flat pane of glass. The part is
Jan 17, 2011· Back in April 2010, I published an article called "5 Rare Earth Stocks to Hedge Against Chinese Control.". In that piece, I wrote: Because 95% of the world's rare earth elements are produced in China, it is becoming increasingly urgent for developers to find REEs in other parts of the world.
U.S. Geological Survey news release "Going Critical" The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices. The U.S.
Rare element substitution a tricky proposition. ... A key factor in these advances is new materials containing exotic elements such as niobium and tantalum, and rare earth metals including yttrium and dysprosium. As consumers demand ever better products, the question of the sustainability of these critical elements arises: how urgent is the ...

Aug 21, 2018· What are rare earth elements useful for? In the last half of the 20th century, europium, with atomic number 63, came into wide demand for its role .
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
Rare earth metals (also known as rare earth elements) comprise a list of 17 elements, including the 15 lanthanides as well as scandium and yttrium. (However, they don't include other headline ...

"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.
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).
Despite their name, rare earth elements are – with the exception of the radioactive promethium – relatively plentiful in Earth's crust, with cerium being the 25th most abundant element at 68 parts per million, or as abundant as copper.
totalElement manufactures a wide variety of strong high-quality neodymium rare earth magnets. Located outside Denver, Colorado, we stock more than 20 million individual magnets in hundreds of different sizes, shapes and strengths. In addition, we can .
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 .
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).
