Rare earths are critical to numerous materials and applications underpinning modern civilisation. The majority of the world's rare earth reserves are hosted in the three minerals bastnasite, monazite and xenotime. A key step in the processing of rare

The influence of sulfate versus chloride media on the adsorption of rare earth elements (REE) by strong acid and iminodiacetic acid resins was investigated. For the strong acid resin, Lewatit MonoPlus SP 112, the adsorption constants recorded for La,

This work examines the extraction of rare earths (Ce, Pr, Nd, Sm, Tb, Dy, Ho, Er, Yb, Lu and Y) by 2-ethylhexyl phosphonic acid 2-ethylhexyl mono-ester (EHEHPA), Cyanex 272, Cyanex 572 and mixtures of EHEHPA and Cyanex 272, to determine whether the m

Uranium is extracted from ore bodies by leaching with either sulfuric acid or sodium carbonate/bicarbonate (alkaline) solutions. Alkaline leaching is usually preferred for ores with gangue compositions that would otherwise result in excessive acid co
