Iron-oxidizing bacteria are present within the top 2 m (but not always at the surface) and near the water table-capillary fringe of the vegetated Nordic uranium deposit, Elliot Lake, Ontario, Canada. They are distributed uniformly in the top 0.5 m of unvegetated tailings. The locations of these bacteria correlate with zones of pyrite oxidation as delineated in previous studies by the formation of soluble iron and sulfate. Heterotrophic bacteria are also present in the tailings, with greatest concentrations at the surface and near the water table-capillary fringe. Sulfate-reducing bacteria were detected in the soil and peat at the base of the tailings. The results of this study suggest that the establishment of vegetation directly upon the tailings surface does not arrest bacterial pyrite oxidation.
铁氧化菌存在于植被覆盖的加拿大安大略省埃利奥特湖北欧铀矿床的顶部 2 米范围内（但并非总是在表面），并靠近有地下水位毛细管边缘。它们均匀分布在无植被尾矿的顶部 0.5 米范围内。这些细菌的位置与以前研究中通过形成可溶性铁和硫酸盐来划定的黄铁矿氧化带相吻合。在尾矿中也存在异养细菌，其浓度在表面和靠近地下水位毛细管边缘处最大。硫酸盐还原菌在尾矿底部的土壤和泥炭中被检测到。本研究结果表明，直接在尾矿表面建立植被并不能阻止细菌对黄铁矿的氧化。
