Abstract

The article presents the results of studying the material composition of the original sample and the data of technological tests. The authors established that the presented raw materials are difficult for enrichment. Mainly it consists of clay minerals with a particle size of less than 20 microns. The coal is found both in the form of individual grains and in the form of mineral aggregates. In the process of carrying out technological tests according to the gravitational enrichment scheme, it was possible to additionally obtain a coal product from the raw material.
