Abstract
It was established experimentally that the trace elements that are present in brown coal samples in low and ultra-low concentrations are concentrated in the finest fraction of the samples whose particle size is smaller than 1 μm (in a submicron fraction), which was separated using special nanotechnological techniques. A comparative analysis of the concentrations of chemical elements in the gross samples of coal and in the submicron fractions showed the special features of the distribution of trace elements in a coal matrix and prospects for the extraction of potentially valuable elements from coals.
