China 'huffs and puffs' on rare earths, but history

May 30, 2019One rare earth trader warned Fastmarkets that history has shown us that China can use rare earths supply as a weapon if it feels threatened. The threat of a rare earth export embargo is not new. In 2010, China attempted to cut off rare earth exports to Japan after a dispute over the ownership of a group of islands in the East China Sea, which

Rare Earths and China A Review of Changing Criticality in

A combination of supply concerns and spiking prices which for some rare earths rose by 500 percent or more in the year that followed drove an investment boom in rare earth exploration that would include the jungles of Brazil, the depths of the Pacific Ocean and even the surface of the moon.

Daily Memo More on Tariffs, More on Rare Earths

Jun 01, 2019If the process is indeed viable, it would presumably deepen Chinese dominance, at least in the short term, over the rare earths industry dominance that Beijing is seeking to use as leverage to get the U.S. and other countries taking aim at Chinese tech firms to back off. But one of the biggest constraints on the development of rare earth mining and processing operations outside China is their

Constraints on partial melting imposed by rare earth

Thirty‐one basalts from Mauna Kea collected through the Hawaii Scientific Drilling Project have been analyzed by inductively coupled plasma (ICP) mass spectrometry for rare earth element (REE) concentrations. The systematic variations in REE abundance provide constraints for theoretical models of mantle partial melting.
