source:MiningWe take a look at neodymium, a not-so-rare rare earth mineral vital in the production of powerful permanent magnets, lasers and aerospace alloysWhat is Neodymium?Neodymium is a rare earth element with atomic number 60 and symbol Nd. It is a soft, silvery metal that tarnishes in air and is one of the most abundant rare earth elements. Neodymium is not found in its pure form in nature but occurs in various minerals, primarily monazite and bastnasite ores.It is classified as a light rare earth element, along with lanthanum, cerium, praseodymium, samarium, and europium. Despite being ...

source:Australian Institute for Bioengineering and NanotechnologyThese jars are full of toxic red mud – a waste material produced by the tonne at mining sites across Australia. In this form, it’s not much use to anyone.But adding the right type of bacteria can help detoxify the sludge, and allow University of Queensland researchers like Dr Rosie Gillane, Fernanda Soto, and Luke Webster to extract valuable rare earth fragments. “You wouldn’t usually associate bacteria or microorganisms with mine rehabilitation,” says Luke, whose PhD thesis is focused on ‘synbio’ mining technique...

Stoichiometric Lanthanide Compounds with Diglycolamides: A Synthetic Approach toward Understanding Rare-Earth Speciation in Solutionsource:ACS PublicationsA fundamental understanding of coordination chemistry across the lanthanide series is essential for explaining the chemical behavior of rare-earth metals in complex liquid–liquid extraction processes. Probing the exact bonding between the extractant and the metal is sometimes done through the synthesis of solid-state compounds that can serve as models for metal speciation in solution. In the case of diglycolamide (DGA), a commonly used neutr...

Novel recycling process for rare-earth elements could improve green technology and boost carbon neutrality source:TechploreIn a recent study published in Engineering, researchers from Kyoto University have unveiled a novel method for the efficient separation and recycling of rare-earth elements (REEs) from end-of-life magnets. This innovative process, known as the selective extraction–evaporation–electrolysis (SEEE) process, promises to significantly advance recycling technology and support global efforts towards carbon neutrality.REEs, particularly neodymium (Nd) and dysprosium (Dy), are...
