The article outlines the problem of ash accumulation in dumps during the combustion of coals at thermal power plants, materials for studying the mineral composition of ash, and also the rationale for the efficiency of a non-waste complex processing of dumps. The quantitative analysis of ash samples from the TPP dumps was carried out, the percentage of iron, carbon and silicate part in all samples was revealed. A complex method for non-waste processing of dump and daily fly ash was proposed. The results of dewatering of the dumping ash on a vibrating device using the electrokinetic method are presented.
