Rare earth minerals, though not actually rare, have unique chemical properties that make them essential for wide-ranging technologies, including smartphones, hybrid cars and high-tech weapons. Two
Rare earth metals are critical to the modern economy. They are the key material for making batteries that power electric vehicles; added to touchscreens and circuit boards in smartphones; and used in laser systems that guide missiles and bombs.
A November 2012 story in Mother Jones magazine reveals that mining rare earth elements, used in all of our smart phones, requires extractors to separate them from the radioactive elements thorium and uranium, with which they are always found. Managing the radioactive waste, once it's separated from the rare earths, is a huge problem, often managed badly, allowing radiation harm to nearby residents or
Rare Earth magnets are the strongest type of Rare Earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These disc magnets are 1/8 in. diameter and 1/16 in. thick.
Sep 16, 2014Scarce or not, rare elements are big business and have inspired the launch of a few companies interested in mining asteroids for these metals. With Apple's report that 4 million iPhone 6 preorders were placed within the first 24 hours, you can bet that the chemistry of smartphones will only become more complex as advanced materials and
Our global thirst for the rare earth elements used in everything from cell phones to hybrid cars has never been higher. But, these crucial minerals can be very hard to access.
Mar 26, 2013Rare earths are a group of 17 chemically similar elements crucial to the manufacture of many hi-tech products. DNews is a show about the
Apr 06, 2016New technology is requiring less expensive and rare metals. A final solution to protecting the future of both solar power and the metals it requires is to find alternative materials. Some new photovoltaic technology uses less-expensive and abundant metals such as zinc and copper in place of "rare earth" metals like Gallium and Indium.

RARE EARTHS—2001 61.1 RARE EARTHS By James B. Hedrick Domestic survey data and tables were prepared by Heather A. Geissler, statistical assistant, and the world production table was prepared by Glenn J. Wallace, international data coordinator. In 2001, rare-earth production was primarily from the rare-earth mineral bastnsite.
As new technologies come online, mining companies are probing depths from 5,000 to 16,000 feet to expose new deposits of manganese, copper, cobalt, and other rare-earth minerals necessary to build everything from smartphones to solar panels to electric cars.
This statistic depicts the distribution of rare earth production worldwide by country as of 2017. At that time, China produced a 78.65 percent share of the total global rare earth mine production
Rare Earth Metals. Among these less-commonly-known elements is the collection of elements nicknamed rare earth metals. These metallic elements have many important uses, such as Rare earth metals are used in heat-resistant, powerful, permanent magnets. Rare earth metals are used in superconductors for cryogenics applications.
The rare-earth elements, or rare earths—the group of 17 chemical elements with atomic numbers 21, 39, and 57 through 71—are not truly rare in terms of their chemical abundance in the Earth's crust. However, they are typically found in low concentrations in ore and mineral deposits, and the current supply of them is somewhat limited.
The US has excluded rare earths from its final list of tariffs against $200bn of exports from China, a decision that highlights the country's reliance on Chinese supply of the niche elements
Rare earth minerals mined for the production of smart phones have filled a lake with black sludge near this industrial city eight hours west of Beijing, China. The sludge cascades from pipes ringing the massive artificial lake. The pipes come from factories that refine the minerals neodymium
In today's Academic Minute, Dr. Cornelia Class of Columbia University explains the importance of rare earth elements in the manufacture of electronics.
Image caption Mobile phones incorporate a wide range of the rare earth elements . There are many more locations on Earth where these critical metals can be mined, including varied geological
Rare earth metals — those 17 chemically similar elements at the bottom of the periodic table — are in almost every piece of technology we use from cell phones to wind turbines to electric cars. Because these elements are so similar to each other, the process of separating them is time consuming, expensive, and dangerous.
Baotou is the world's biggest supplier of rare earth minerals — the fundamental ingredients used to make today's technologies — and it's hell on Earth.
