The physicochemical analysis of distribution of useful components in processing of ash and slag of the thermal energy sector plants is performed. The article describes thermodynamics and kinetics of chemical reactions during agglomeration of feedstock and ammonium hydrofluoride at the temperatures of 50–200 °C, sublimation of ammonium hexafluorosilicate in the temperature range of 350–550 °C, production of amorphous silica nanoparticles, alumina particles and red iron oxide pigment, as well as formation of calcium fluoride (Ca, Y)F 2 which is a concentrator of rare and other elements. The efficient technology is developed for processing of electromagnetic fraction of ash and slag with integrated recovery of various useful components.
