Pioneering new research has helped geologists solve a long-standing puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits.


A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

The elements are among the most sought after, because they are an essential part of digital and clean energy manufacturing, including magnets in large wind turbines and electric cars motors.

For the new research, scientists conducted a series of experiments that showed sodium and potassium—rather than chlorine or fluorine as previously thought—were the key ingredients for making these rare earth elements soluble.

This is

A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

For the new research, scientists conducted a series of experiments that showed sodium and potassium — rather than chlorine or fluorine as previously thought — were the key ingredients for making these rare earth elements soluble.

This is crucial as it determines whether they crystalise — making them fit for extraction — or stayed dissolved in fluids.

The experiments could therefore allow geologists

Metallic carbon circuit element enables work on faster, efficient carbon-based transistors — ScienceDaily

Transistors based on carbon rather than silicon could potentially boost computers’ speed and cut their power consumption more than a thousandfold — think of a mobile phone that holds its charge for months — but the set of tools needed to build working carbon circuits has remained incomplete until now.

A team of chemists and physicists at the University of California, Berkeley, has finally created the last tool in the toolbox, a metallic wire made entirely of carbon, setting the stage for a ramp-up in research to build carbon-based transistors and, ultimately, computers.

“Staying within the same material, within the realm of carbon-based materials, is what brings this technology together now,” said Felix Fischer, UC Berkeley professor of chemistry, noting that the ability to make all circuit elements from the same material makes fabrication easier. “That has been one of the key things that has been missing in the big

VANCOUVER, British Columbia, Sept. 25, 2020 (GLOBE NEWSWIRE) — Medallion Resources Ltd. (TSX-V: MDL; OTCPK: MLLOF; Frankfurt: MRDN) – “Medallion” or the “Company”), is pleased to announce the initiation of a comprehensive comparative technical and commercial review of existing and emerging rare-earth element (REE) separation technologies.  

Medallion’s REE extraction process from monazite has achieved the technical milestones needed to consider binding downstream partnerships, while the Company’s improved financial position is enabling stronger commitments within the REE supply chain. Leading technologies, subject to appropriate business conditions, will be considered for partnership or investment by Medallion or its North American focused REE Consortium financial backers Talaxis Limited, (the technology metals unit of Noble Holdings) and Amvest Capital Inc., both significant Medallion shareholders.

“Medallion has identified four leading and approximately ten additional groups with potential technologies for REE separation, alongside the industry incumbent
