The chemical and granulometric composition, as well as the physical and mechanical characteristics of various CHPPs ash were studied. Revealed features provided the development of ash enrichment technologies. The components of ash and slag wastes of Seversk CHPP can be separated using a combination of techniques such as dehydration, vibration and gravity classification applying hydrocyclones, vibrating screens, centrifuges. Obtaining components have various sizes; they are suitable for use in construction.
