Trace elements in red mud were assayed with fused lithium borate glass beads using Xray fluorescence spectrometry. Low dilution glass beads, which had a 1:4 sample-to-flux ratio, were prepared for determination of elements. Complete vitrification of 1:4 mixture required heating at 1150°C with agitation. Extra pure reagents containing determinants were used for calibrating standards instead of the red mud standard. The calibration curves of the 15 elements showed good linearity.The study was financially supported by the Ministry of Education and Science of the Russian Federation within the framework of subsidizing agreement of September 29, 2014 (no. 14.581.21.0002, unique agreement identifier RFMEFI58114X0002) of the Federal Target Program ...
