Abstract: Assessment of precious metals content in coals and ash and slag waste of thermal power plants is carried out. Methods of obtaining gold concentrate from ash and slag waste are considered. The data on amounts of precious metals, accumulated in ash dumps of large Far East thermal power plants are presented. The technology of selection of ash and slag materials with increased gold concentration from an ash handling system of thermal power plant for further enrichment is suggested.
