Chemical analysis of BaSO_4 in barite bearing concentrates and beneficiation products by wavelength dispersive X-ray fluorescence spectrometry

摘要

The chemical analysis of Ba in barite bearing matrix (concentrates and beneficiation products) by wavelength dispersive X-ray fluorescence spectrometry is reported to be affected by spectral interference of Ti. The work suggests that the analysis is affected by the mineralogical heterogeneity leading to chemical heterogeneity of the secondary standards. Such heterogeneity is more probable in the samples having lower content of heavy minerals of high specific gravity.
