Chemical analysis of BaSO4 in barite bearing concentrates and beneficiation products by wavelength dispersive X-ray fluorescence spectrometry

The chemical analysis of Ba in barite bearing matrix (concentrates and beneticiation products) by wavelength dispersive X-ray fluorescence spectrometry is reported to be affected by spectral interference ofTi. 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 gmvity.
