A PRELIMINARY REPORT ON THE SOLVENT EXTRACTION OF BERYLLIUM FROM LOW GRADE SULPHATE AND FLUORIDE SOLUTIONS
Technical Report

OSTI ID:4828147
Beryllium was extracted from sulfuric acid leach liquors using kerosene solutions of both di-(2-ethylhexyl) hydrogen phosphate and monododecyl dinydrogen phosphate. Ferric iron and aluminium were also extracted, the order of preference being Fe > Be > Al. Iron and aluminum once extracted are not readily dlsplaced by beryllium. The stripping of all three metals from the phosphate esters was examined briefly. It was not found possible to extract beryllium from fluoberyllate solutions with the phosphate esters tested. Kerosene solutions of high molecular weight amines did not extract beryllium from fluoberyllate or from sulfate solutlons to any useful extent under the conditions studied. (auth)
