• Hydrozincite exhibits significant control on heavy metal mobility in other abandoned mining sites. No morphological similarity between biomineralized hydrozincite and Victoria Mine. Microbiological effects attenuation aqueous geochemistry are negligible. Microbial growth patterns community structure represent oligotrophic conditions. Large-scale Zn, Pb, Cu, Fe Ag ceased over 70 years ago the ...

Acid mine drainage (AMD) still represents a huge environmental problem. Technical and scientific breakthroughs are needed to decrease damages, treatment cost, waste production associated with AMD. The feasibility of combining continuously fed anaerobic sulfate-reducing bioreactor downstream iron oxidation step was tested, at laboratory scale, two types real arsenic-rich AMD waters from the site...

The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...

A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

Altogether 20 groundwater samples were collected around the Lakan Pb and Zn mine in Iran. Samples were analyzed for 8 constituents including Fe, Pb, Hg, Mn, Zn, CN, SO4 and Cl using standard method. The results show that the average concentrations of constituents were 0.01, 0.60, 0.10, 0.01, 0.40, 35, 0.01 and 5.95 mg/kg for Fe, Mn, Pb, Zn, Hg, SO4, CN and Cl, respectively. The computed contami...
