A Direct Non-destructive Method for Determination of Sulfur in Ore Samples Using EDXRF Spectrometry

A method has been developed for direct non-destructive energy dispersive X-ray fluorescence (EDXRF) determination of sulfur in solid uranium ores and intermediates, obtained from the alkaline recovery process its ores. The involves thorough grinding a few mg powder samples to fine particle size mixing thus with drops 10% collodion solution amyl acetate make paste. very small amount this paste was transferred help pestle tip, spread uniformly form thin slurry on Mylar films, dried sample specimens film supports. These were presented EDXRF measurements. calibration plot made by plotting intensity ratios S Kα Rayliegh scattered peak excitation source (Ge Kα) against sulphur percent certified reference materials (CRMs). It found that precision using methodology within 5% (±1σ) deviation analytical results expected values CRM 7%. successfully applied different stages ore processing based leaching method.
