In this paper an accurate and highly reproducible separation method for determination of trace amounts of uranium and rare earth elements (La-Lu and Y; abreviated as REEs) in the refractory zircon mineral concentrates by inductively coupled plasma-optical emission spectrometer (ICP-OES) is described. The precipitation method used for separation of zirconium is simple, selective, rapid and environmental friendly. All the 16 geochemically important analytes were determined in a single solution with marginal improvement in detection limits (1.2-4.5 times) after separation. The method was validated by analyzing certified reference materials.
