The mining operations in the uranium deposit Curilo were concluded in 1990, but since then, the site has posed a persistent issue with acid drainage waters. These waters, characterized by a low pH, typically ranging from 2 to 3, contain significant levels of pollutants including uranium, radium, toxic heavy metals, arsenic, and sulfates, often exceeding permissible limits by 2-5 times. Acid drainage is primarily generated through the bacterial oxidation of residual pyrite and various uranium minerals left from mining activities. This paper presents findings on the generation of acid drainage following rainfall events at a mine dump, revealing a diverse microflora dominated by chemolithotrophic bacteria. Moreover, the study identified crucial environmental factors such as pH, temperature, and moisture levels that significantly influence microbial activity within the dump. These insights highlight the ongoing environmental challenges posed by former mining operations and the role of microbial processes in acid drainage formation.
