    AnnotationAcid mine drainage (AMD) is the product of the natural oxidation of sulphide minerals. The simultaneous influence of water, oxygen and indigenous microorganisms represents the necessary conditions for AMD formation. The occurrence of AMD is associated mainly with the presence of sulphide minerals in the polymetallic, coal and lignite deposits. AMD contaminates the groundwaters and soils because it contains mainly sulphuric acid, heavy metals and metalloids. During the exploitation, and mostly after the mine closure, the produced AMD pollutes the environment. The continuance of AMD generation is difficult to halt. Self-improvement situation is not possible. It is necessary to monitor the quality of AMD and develop the methods of their treatment. Slovakia belongs to the countries copper, gold and silver. Currently, only one deposit is being exploited, namely, Au-ore deposit in Hodruša. The other deposits are mostly flooded. They present the suitable conditions for creation and intensification of chemical and biologicalchemical oxidation of the sulphide minerals, i.e. formation of AMD. In Slovakia, Smolník and Pezinok deposits, as well as the Šobov dump, are typical examples of the old mining loads with production of AMD
