Today, coals can also be considered as an economic source of a number of critical elements. In the Irkutsk region, coal mining is provided by the resources of the Irkutsk coal-bearing basin. The concentrations of the main and microelements in coals and clay interlayers of the Karataevsky, Aransakhoy and Cheremkho deposits, and the dump and concentrate of the coal of the Kasyanovskaya enrichment plant were determined by X-ray fluorescence analysis. A weak Y enrichment, with an average concentration 2-3 times higher than in the average world coal, was determined in the Irkutsk coals. Elevated concentrations of Ni, which exceed the average value for world coals by an average of 15 times, was determined in the Aransakhoy deposit. Also, the Irkutsk coals are characterized by a weak enrichment of Ge, about 2 times higher average world coal. The studied coals contains elevated concentrations contents of potential environmental hazardous elements (F, Th, Pb), which should be considered during recultivation and waste management. Decrease Pb concentrations in the obtained coal concentrate is noted in comparison with the original coal dump used as the starting material for producing the concentrate, according to the results of studies of the dump and concentrate of the Kasyanovskaya enrichment plant coal.
