source:Journal of Sustainable MetallurgyHimanshu has conducted in-depth research on the recovery of Ti, Al and RE (Sc, Y, La and Ce) from bauxite slag by sulphation roasting process.The Bayer process for alumina production generates more than 160 million tons of bauxite residue annually. The currentglobal stockpiles of bauxite residue have reached more than 4 billion tons with less than 2% annual recycling rate. Criticalelements such as Sc and Y present an opportunity to explore bauxite residue as a secondary resource; however, low concen-tration affects the process economics.Recovery of major...

source:innovationnewsnetworkIntegrating the concepts of Radioactive Waste Management with Life Cycle Analysis towards a circular economy.Radioactive waste is a by-product from nuclear reactors, fuel processing plants, hospitals, and research facilities. It is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities. Radioactive waste comes from many sources, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare earth mining, and nuclear weapons reprocessing.1,2In France, the classification is done based o...

source:financeIn mid February 2023 Renforth's geologists spent one day on a prospecting effort in the powerline cut corridor at Surimeau, approximately 4km south of the ~20km long Victoria polymetallic battery metals mineralized system, within the Decelles batholith margin. Snow cover was more significant than anticipated and mixed with ice layers. As a result of this only two samples were obtained, one consisting entirely of pegmatite, one of a mix of pegmatite and granite. The samples were both tested with an XRF, which resulted in elevated rare earth element readings. The samples have b...

source:scitechdailyWith strong reducibility and high redox potential, the hydride ion (H-) is a reactive hydrogen species and an energy carrier. Materials that conduct pure H- at ambient conditions will be enablers of advanced clean energy storage and electrochemical conversion technologies.Several H- conductors have already been developed in recent years, but none of the materials could achieve superionic conduction at ambient conditions.The research team targeted the structure and morphology of trihydrides — hydrides containing three atoms of hydrogen per molecule — of certain rare earth ele...
