Rare earth minerals could help in climate change fight, but mining raises environmental concerns: expert source:cbc.caWhile rare earth minerals are now being touted as a key part of efforts to reduce greenhouse gases, there are environmental concerns in extracting these minerals from the ground, says an expert in environmental considerations around mining.Demand is growing for rare earth elements — a group of metals and minerals that includes lithium, graphite, nickel, cobalt and copper that are used in batteries for everything from vehicles to smartphones.Rare earth elements are being pr...

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...

source:hurriyetdailynews“As the name suggests, these elements are rarely found around the world,” Dönmez said on Jan. 28 at an event titled “Energy Goals in Century of Türkiye” in Istanbul.“There are 17 rare elements in the periodic table, and we found seven-eight of them in Beylikova [in the Central Anatolian province of Eskişehir]. 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...
