X-Ray Emission Spectrographic Analysis of Bastnaesite Rare Earths

摘要

An X-ray emission spectrographic method of analysis is presented for determin¬ing rare-earth elements in fractions obtained from bastnaesite ore. The method includes determination of yttrium, thorium, lanthanum, and the rare-earth elements in various complex mixtures. The analysis technique is based upon comparing the samples with synthetic standards approximating the composition of the samples.
