Development of alternative energy sources are increasing now, but the use of minerals still plays an important role in the industrial sector, and Ukraine is no exception. DTEK Energo is a key player in Ukraine's coal industry. 13 mines and 4 coal concentrators represent production capacities of this segment. Dumps and sludge storages contain about 1.3 billion tons of rocks with an annual replenishment of about 60 million tons. These areas occupy large areas and require reclamation in the future. This paper presents the results of physico-chemical analysis of DTEK SU "Heroiv Kosmosu" coal mining dump, namely such indicators as: pH and electrical conductivity of the substrate (EC), nutrient content, concentration of rare earth elements. The results of the obtained data in the future allow to choose the best method of reclamation, involving plants, with subsequent bioleaching of rare earth metals.
