Neodymium and samarium—two of the 17 rare earth elements—are ferromagnetic, meaning that they have inherent magnetic properties and can be magnetized. These metals are first mined, refined, …

Laudal and colleagues have demonstrated they can generate a product with 60 to 90% (600,000 to 900,000 ppm) rare earths from lignite. They are now scaling up their solvent extraction process to a ...

REEs in EVs REEs are in many parts of Evs: motors, NiMH batteries, windows, glass, catalytic converters, electronic equipment. The technologyforEvs Rare Earth Permanent Magnet It stimulates the flow of electrons from one atom to another; and by doing so, it can generate a substantial amount of electrical energy.

Rare earths are also driving the growth of green technologies, such as wind energy and electric vehicles, and may even give rise to new components for quantum computers. "The list just goes on ...

Rare earth elements are widely distributed throughout the earth's crust, but generally in low concentrations. The concentration of individual REEs depends on the type of mineral deposit being mined, and REEs are often found alongside radioactive elements such as thorium and uranium (Rhodes 2011).

The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's crust at 60 parts per million, to thulium and lutetium, the least abundant rare-earth elements at about 0. ...

Last year, the EU kick-started 10 billion euros ($12 billion) of investment into rare earth and other green-energy-related projects, and it says its demand for rare earth metals could surge as ...

Rare earth-enabled technologies power global economic growth, enable life-saving products, and help shrink our carbon footprint.

The rare earths have become crucial to modern life, but our dependence on them is mostly invisible to American consumers.

Around 2010, many commentators stridently warned that China's near-monopoly on supermagnet rare-earth elements could make the growing global shift to electric cars and wind turbines impossible—because their motors and generators, respectively, supposedly required supermagnets and hence rare earths. Some such reports persist even in 2017.
