vanadium separation is difficult as it can also be absorbed strongly by the commercially used ion exchange resins (du Preez 1989, Dry 2009). Until now, no solvent system has been found suitable for uranium extraction from alkaline carbonate solutions. A number of quaternary amines were studied (Moore et al. 1955, Crouse et al. 1956). It was shown that no quaternary amines performed well with ...
