The article presents the results of the research on mining production waste in the Chervonohrad Mining Area. For the first time the water extracts from certain types of waste rock, namely: burned and unburned argillite, siltstone, siliceous siltstone, coal, and sandstone were investigated. The studies covered the main chemical composition, as well as the pH and concentration of the main components of the aqueous extracts. Based on the obtained results, the properties of the investigated mining wastes were characterized, taking into account the impact on the environment. According to the obtained results, it can be stated that there is high content of Mg2+, SO42-, HCO3- in argillite and sandstone within the tericon of the central coal enrichment plant “Chervonohradska” and burnt argillite from the tericon of the Vizeyska mine.
