СOST-EFFECTIVE TECHNOLOGY FOR HEAT POWER STATIONS ASHES PROCESSING AND UTILIZATION

The heat power stations (HPS) ashes generated by the burning of coal are on the one hand,
the source of environmental pollution. On the other hand, they pose the source of raw materials for
industry. There have been accumulated hundreds of millions tons of ash in Ukraine’s HPS ash
disposals, still containing a number of valuable components. Furthermore, HPS disposals are
annually filled with fresh ash inflow of more than 10 million tons. Despite the content of phase
terms with high consumer properties in a number of ashes is relatively high, we can only partially
assign them to technogenic minerals due to the lack of cost-effective methods of valuable
components recovery. Therefore limited quantities of HPS ashes are used up to the present.
