source：MINING.com-An international team of researchers published a paper in Science stating that the global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals.According to the scientists, the main risk emerges from the fact that global supplies of cobalt, copper, lithium, cadmium, and rare earth elements needed for solar photovoltaics, batteries, electric vehicle motors, wind turbines, fuel cells, and nuclear reactors tend to be heavily monopolized by a single country, ...

source：Phys.OrgScientists from the U.S. Geological Survey (USGS) have mapped a rare earth element deposit of magmatic carbonatite located in the Mountain Pass region of the eastern Mojave Desert. The new report details the geophysical and geological setting of the deposit, including a map of the deposit's subsurface extent, to help land-use managers evaluate sites for further exploration. The report was recently published in the Geological Society of America's online journal, Geosphere.Rare earth elements (REEs) are critical to emerging industrial technologies including strategic defense, scie...

source：ChemEngOnlineSmall-scale pilot testing has begun for a process that extracts nickel, manganese, cobalt and copper from nodules collected from the surface of the Pacific Ocean seafloor. Obtaining the metals from the seabed nodules has advantages over mining land-based ores because the nodules contain far less toxic heavy metals and can be processed with zero tailings, according to process developer DeepGreen Metals Inc. (Vancouver, B.C.; www.deep.green).The nodules are formed on the seafloor four to six km deep in the Clarion-Clipperton Zone, a region of the Pacific Ocean between Hawaii ...
