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.
