We investigate correlations between content of As, Sb, Zn, Cu, Fe and microbiological composition of the wastes in the vertical and horizontal directions at the Komsomolsk tailings, Kemerovo region, Russia. Concentrations of As up to 30 g/l and Sb up to 91 mg/l were revealed in pore waters. Seventeen strains were cultured from the wastes. The northern part of Komsomolsk tailings is characterized by a large amount of bacterial diversity in the wastes. Among Gram-positive bacteria, there is domination of Bacillus. The positive correlation between concentrations of As and Bacillus subtilis and Bacillus globigii indicates the role of the bacteria in the formation of the secondary mineral phases of Schneiderhohnite, detected in the wastes composition.
