source:phys.orgResearchers at Oak Ridge National Laboratory have zoomed in on molecules designed to recover critical materials via liquid-liquid extraction, or LLE—a method used by industry to separate chemically similar elements.The team had previously designed a novel ligand, or collector molecule, to grab select lanthanides from rare-earth mineral solutions.Lanthanides are rare-earth metals critical to energy and national security technologies for magnets, electronics and catalysts. They occur together naturally in mineral ore deposits, but their chemical similarities make separating indivi...

source:phys.orgCritical Materials Institute researchers at Oak Ridge National Laboratory and Arizona State University have studied the mineral monazite, an important source of rare-earth elements, to enhance methods of recovering critical materials for energy, defense and manufacturing applications.Rare-earth elements occur together naturally in mineral ores such as monazite but are economically challenging to recover. New approaches to separate the valuable ore from unwanted materials are needed.The research team combined theory and experiment to gain atom-level insights on monazite, providin...

It is the second greatest discovery in the world.”Rare earth elements will be more important in the future, the minister added.“In the coming period, we will see an unnamed struggle, a war in the field of rare earth elements, just as the energy wars were...

Deep seabed mining plans pit renewable energy demand against ocean life in a largely unexplored frontier source:themandarinAs companies race to expand renewable energy and the batteries to store it, finding sufficient amounts of rare earth metals to build the technology is no easy feat. That’s leading mining companies to take a closer look at a largely unexplored frontier — the deep ocean seabed.A wealth of these metals can be found in manganese nodules that look like cobblestones scattered across wide areas of deep ocean seabed. But the fragile ecosystems deep in the oceans are little un...
