Mineral & Rare Earth Elements Analyzers. Portable X-ray fluorescence (XRF) technology can be used in a wide range of mineralogical and geological exploration markets, one of which is the mining of Rare Earth Elements (REEs). REEs are defined as the 15 lanthanides plus scandium (Sc) and yttrium (Y), and they are critical components in consumer

Apr 01, 2015 It appears that heavy rare earth oxide mining remains focussed on extraction from ionic absorption clays found in southern China. This suggests that light rare earths (Neodymium) will remain at relatively low costs whilst heavy rare earths (Dysprosium) may remain in relatively short supply.
