Prospects of complex processing of the high-siliceous technogenic waste of thermal power plants

On the basis of theoretical and experimental studies of processes of hydrochemical processing of high-siliceous technogenic waste of thermal power plants, the optimum conditions of receiving nanodisperse amorphous silicon dioxide, alumina, a red iron-oxidizing pigment and other commodity products are revealed. The effective method of complex extraction the various useful components from electromagnetic fraction of coal ashes is developed.
