Abstract: The article analyzes the content and composition of waste from coal mining, coal refining and coal enrichment of deposits of the Kuznetsk coal basin. The use of rare earth elements in various industries is considered. The raw material base of rare earths in the Russian Federation and the possibility of using ash and slag waste of a thermal power plant as raw materials for extracting useful components are analyzed. One of the world's largest mineral resource base of rare earth elements is located in the Russian Federation, which accounts for 18 million tons of proven reserves of rare earth elements (in terms of oxides), which is 15% of the global reserves. Coal ash processing is the most relevant for the Russian Federation, since the annual amount of ash and slag waste produced is estimated at 90 million tons (excluding dumps of rocks of the mining industry). At the same time, the accumulated volumes of ash and slag amount to about 2 billion tons. The influence of ash and slag dumps on the ecological situation and the scheme of the impact of these processes on the environment are also considered. Influence of ash and slag waste The contents of matrix, rare and rare earth elements in coal dumps of various regions of Kuzbass were determined. Conclusions were drawn about the possibility of using waste as a raw material for extracting useful components with high added value, and ways of processing each type of waste were determined.
