    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.
