Source:Atlanta MagazineIn 2016, Georgia State University graduate student Danny Gardner wrote a thesis that called for digging a little deeper into materials mined near the town of Sandersville, the self-proclaimed “Kaolin Capital of the World,” two hours southeast of Atlanta. His professor, Dr. W. Crawford Elliott was curious. Together, they visited the vast white mines, collected samples from their corporate sponsor Thiele Kaolin Company, and returned to their lab in downtown Atlanta. There, they discovered something mixed in the dusty powder and rocks that Elliott describes as remarkable: a...

Source:GizmodoOffshore wind power seems to be on the cusp of taking off in the U.S. That’s great news for the climate, but every technology has a cost. As a new study points out, a surge in offshore wind could also mean a surge in our appetite for a rare earth metal that’s mined at a heavy environmental toll.In fact, expanding U.S. offshore wind capacity in line with a recent Department of Energy report could require some 17,000 tons of the rare earth metal neodymium by 2050, according to the paper published recently in Nature Sustainability. This demand, equivalent to that of about 20 million...

Source:Phys.OrgFrom computer hard discs and smart phones to earbuds and electric motors, magnets are at the forefront of today's technology. Magnets containing rare-earth elements are among the most powerful available, allowing many everyday objects to be ever smaller. But rare-earth elements can be difficult to obtain, given either their scarcity or the challenging geopolitical climates of some of the nations where they are mined. Now, scientists have identified magnets based on more readily obtainable rare earths, as well as some promising magnets that don't contain these materials a...
