Cd. The analysis of data shows that when using the
ratio of the intensities of coherently and incoherently scattered X-radiation of the excitation source the
dependence of the analytical line intensity of niobium on the content of W in the samples is taken into
account. The experimental results confirm the conclusions of the theoretical consideration. This technique
was successfully used to study wolframite samples from the deposits of the Eastern and Western Mongolia.
A procedure for the determination of Cu, Mo and Fe concentrations in ores, copper and molybdenum
concentrates, and enrichment waste was developed to control the process of enrichment at the mining
company “Erdenet”, Mongolia. This procedure was based on using regression equations. The form of
regression equations was chosen based on the theoretically calculated intensities. The comparison results
of measurements using the newly developed technique and the standard-background method are presented.
Keywords: X-ray spectral fluorescence analysis of ores and enrichment products, method of
standard-background, theoretical simulation of matrix effects.

1. INTRODUCTION
The study of the distribution of impurity elements in
the ore minerals allows to reveal a number of regularities
of mineralization. For wolframite deposits tantalum,
niobium, and scandium are of particular interest from
this point of view. It was found that in some cases the
376
wolframites can be an additional source of niobium,
tantalum, and scandium [1, 2]. It was also found that the
content of these impurity elements and their ratios can
inform about the conditions of formation of wolframite
deposits. On the other hand, the chemical methods
for the separation and determination of Ta and Nb in
wolframites are laborious.
The applicability of coherently and incoherently scattered radiation was investigated on the example
of quantifying the Nb content in wolframite. The calculated and experimental intensities of NbKa
-line for
with various matrices have been compared. The major
