Abstract:

Purpose. Studying the distribution of impurity elements in the coals of the Shubarkol deposit to assess their geochemical specialization, as well as to forecast their industrial potential.

Methodology. The research methodology is based on the results of analytical studies carried out by the instrumental neutron activation (INAA) method, as well as microscopic studies carried out on the basis of the nuclear-geochemical laboratory of the Department of Geoecology and Geochemistry of National Research Tomsk Polytechnic University. These data became the basis for establishing the patterns of distribution of impurity elements in coals.

Findings. It is found that the coals of the Shubarkol deposit are geochemically specialized in Ba, U, Au, Yb, Ba, Cd, La, Nd, Ce, Zn, Sc, Sr, Zr. The weathered coals of the Eastern section of the deposit contain concentrations of Ce, Ba, Yb, U, Sc, Au that are higher than those in the Central and Western sections and reach industrially significant amounts. Recommendations are given for the extraction from the coals of uranium and rare-earth elements of the yttrium group having industrially significant contents.

Originality. Regularities of the impurity elements distribution using the methods of INAA and microscopy are established; the potential of coals as an unconventional source of a number of chemical elements is determined, and the possibility of their complex extraction is evaluated.

Practical value. It consists in substantiating the possibility of the integrated use of coal from the deposit, which ensures the development of the country’s coal industry.
