Abstract
The article substantiates the importance of using coal enrichment methods, which allow you to obtain high-quality coking and energy coals that contribute to the improvement of the quality of coal raw materials at the present stage, increasing their demand, both in the domestic and foreign markets. It was revealed that not all the methods presented by modern technology of coal enrichment are applicable for the disposal of coal production waste. The analysis allows us to argue that Russian enrichment factories must pay attention to the modernization of capacities for the enrichment and sorting of coal for carbon enrichment equipment of domestic production. In this regard, in order to reduce the volume of hydraulic explosives in order to extend their operational period and reduce the environmental load on the environment and to obtain an additional commodity product, special technologies are needed that contain environmentally friendly methods of enriching technogenic raw materials. The authors are invited to use the unique technology of dry enrichment of coal, which is currently used by Sun Energy together with Russian partners.
