Determination, by X-Ray-Fluorescence Spectrometry, of Tin and Tungsten in Ores, Concentrates, and Residues of Scheelite, Wolframite, and Cassiterite.

摘要

The determination of tin and tungsten in ores and concentrates consisting of mixtures of scheelite and cassiterite, or of wolframite and cassiterite, is very important to the production of these minerals in Southern Africa. Several methods using X-ray-fluorescence spectrometry (XRFS) have been developed for the determination of tin and tungsten.
