Analysis of the Chemical Composition of Ash and Slag Waste of TPP in the FarEast District of Russia as Technogenic Deposits of Precious Metals

摘要

Assessment of precious metals content in coals and ash and slag waste of thermal power plants iscarried out. Methods of obtaining gold concentrate from ash and slag waste are considered. The data onamounts 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 handlingsystem of thermal power plant for further enrichment is suggested.
