The coal waste from power stations in the north and south of the Kuznetsk Basin are compared in terms of their suitability for concrete production and as a source of valuable components. The mean aggregate content of rare and rare-earth metals in ash and slag waste in the Kemerovo region is 0.02–0.04%; the content of matrix elements is up to 65%. Such waste is promising for the extraction of matrix, rare, and rare-earth metals.
