Abstract: The global growth in energy consumption has stimulated the intensive development of coal mining, which results in the formation of significant volumes of rock dumps and sludge. The accumulation of this waste from the coal mining industry poses important challenges for society: rational use of resources, search for processing methods and environmental protection. Statistical data on the volume of waste from the thermal power sector of leading countries-producers of electricity show that in Russia only a tenth of ash and slag waste is utilized, which is significantly inferior to the indicators of developed countries. An additional environmental burden is created by waste from industrial boiler plants, where, due to technological imperfections of the equipment, there is a high content of unburned carbon, complicating the process of complex processing and extraction of valuable components. A significant part of industrial and consumer waste can be integrated into a closed production cycle of multiple use. At the same time, the quality of recycled secondary raw materials often reaches the level of primary materials, and in some cases demonstrates superior characteristics. Waste recycling helps optimize resource use and minimize environmental impact. Modern science and industry are actively developing innovative ways to use rock waste and sludge, which meets the principles of sustainable development and helps to effectively resolve the issue of recycling these materials. In this paper, the dependence of the destruction rate of rock granules of coal enrichment of JC TsOF "Berezovskaya", formed at various stages of enrichment on the volume of supplied drops, the ratio and feed rate of leaching components was studied. A comparative analysis of rocks showed that BF-5 has a lower resistance to destruction compared to BF-4.
