Analysis of Rare Earths in Eudialyte of Seal Lake, Labrador by Means of X-Ray Fluorescence Spectroscopy

Abstract

<p> The mineral eudialyte from Seal Lake, Labrador, was analyzed by means of x-ray fluorescence analysis for the rare earths La, Ce, Pr, Nd, Sm, Gd, Y and also for the element Zr. Samples were prepared by two methods: a) whole mineral powder being compressed into pellets, and b) the dissolved mineral being put through an ionic exchange process to eliminate interfering ions before compressing into pellets for analysis. The results are compared with published data.on other eudialyte occurrences. </p>
