Abstract:

We have determined the ways of using ash-slag waste of the Ukrainian thermal power plants. The main measures, namely, “dry” methods of separated ash and slag removal, pneumatic ash removal, classification by grain composition, flotation, gravity and electrostatic separation, and other methods of waste processing, can meet the requirements to the quality of ash-slag waste for manufacturing marketable products on their basis. We give a list of current normative documents in Ukraine concerning ash-slag utilization.

Keywords: thermal power plant, ash-slag, waste, utilization, lanthanides, remaking, ionosphere, rare earth elements.
