pH Gradient-Induced Heterogeneity of Fe(III)-Reducing

Lakes formed because of coal mining are characterized by low pH and high concentrations of Fe(II) and sulfate. The anoxic sediment is often separated into an upper acidic zone (pH 3; zone I) with large amounts of reactive iron and a deeper slightly acidic zone (pH 5.5; zone III) with smaller amounts of iron. In this study, the impact of pH on the Fe(III)-reducing activities in both of these

Abstract. The dissolution of sulfide minerals such as pyrite (FeS 2), arsenopyrite (FeAsS), chalcopyrite (CuFeS 2), sphalerite (ZnS), and marcasite (FeS 2) yields hot, sulfuric acid-rich solutions that contain high concentrations of toxic metals.In locations where access of oxidants to sulfide mineral surfaces is increased by mining, the resulting acid mine drainage (AMD) may contaminate
