Rare-earth element

REEs are naturally found in very low concentration in the environment. Mines are often in countries where environmental and social standards are very low, causing human rights violations, deforestation and contamination of land and water. Near mining and industrial sites the concentrations can rise to many times the normal background levels. Once in the environment REEs can leach into the soil where their transport is determined by numerous

Rare earth element metasomatism in hydrothermal systems

Wollastonite ores and garnet-pyroxene skarns in the Willsboro-Lewis district, New York, USA were formed in a complex hydrothermal system associated with the emplacement of a large anorthosite pluton. Contact-metamorphic marbles were replaced by wollastonite, garnet, and clinopyroxene during infiltration metasomatism involving large volumes of water of chiefly meteoric origin.

Does China pose a threat to global rare earth supply chains?

From 2008 to 2018, China exported nearly 408,000 metric tons of rare earths, which amounted to 42.3 percent of all rare earth exports over the period. The United States was the second-largest exporter, supplying roughly 9.3 percent of the global total. Malaysia (9.1 percent), Austria (9.0 percent), and Japan (7.1 percent) rounded out the top five.

Protecting America's Supply of Rare Earth Elements

China quickly became the dominant power in both the mining and the refining of these elements. By 2016, the United States imported all of the rare earth elements we used, mostly from China. During this time uses for rare earth elements expanded, and so did demand. Total U.S. imports rose by more than 14% from 2017 to 2018.

Rare Earth hypothesis

Rare Earth proponents argue that a planetary system capable of sustaining complex life must be structured more or less like the Solar System, with small, rocky inner planets and massive outer gas giants. Without the protection of such "celestial vacuum cleaner" planets with strong gravitational pulls, other planets would be subject to more frequent catastrophic asteroid collisions.

Rare Earth systems in a magnetic field: Coupling of

We study the mutual influence of magnetic and elastic properties of a Rare Earth system as an external magnetic field is applied. It is demonstrated that a magnetic phase transition should show up in the temperature dependence of certain sound velocities. Furthermore the magnetic field should induce a hybridization between the magnetic excitons and phonons.
