  Title (down) Treatment of acid rock drainage in a meromictic mine pit lake Type Journal Article
  Year 2006 Publication Journal of environmental engineering Abbreviated Journal  
  Volume 132 Issue 4 Pages 515-526  
  Keywords Pollution and waste management non radioactive Groundwater problems and environmental effects geological abstracts: environmental geology (72 14 2) geomechanics abstracts: excavations (77 10 10) meromictic lake acid mine drainage mine waste copper water pollution Bacteria microorganisms Canada Vancouver Island British Columbia North America  
  Abstract The Island Copper Mine pit near Port Hardy, Vancouver Island, B.C., Canada, was flooded in 1996 with seawater and capped with fresh water to form a meromictic (permanently stratified) pit lake of maximum depth 350 m and surface area 1.72 km2. The pit lake is being developed as a treatment system for acid rock drainage. The physical structure and water quality has developed into three distinct layers: a brackish and well-mixed upper layer; a plume stirred intermediate layer; and a thermally convecting lower layer. Concentrations of dissolved metals have been maintained well below permit limits by fertilization of the surface waters. The initial mine closure plan proposed removal of heavy metals by metal-sulfide precipitation via anaerobic sulfate-reducing bacteria, once anoxic conditions were established in the intermediate and lower layers. Anoxia has been achieved in the lower layer, but oxygen consumption rates have been less than initially predicted, and anoxia has yet to be achieved in the intermediate layer. If anoxia can be permanently established in the intermediate layer then biogeochemical removal rates may be high enough that fertilization may no longer be necessary. < copyright > 2006 ASCE.

  Title (down) Treatment of acid mine drainage containing iron ions and arsenic for utilization of the sludge Type Journal Article
  Year 2006 Publication Sohn International Symposium Advanced Processing of Metals and Materials, Vol 9 Abbreviated Journal  
  Volume Issue Pages 373-381  
  Keywords mine water treatment arsenic biotechnology filtration iron membranes microorganisms mining industry oxidation sludge treatment acid mine drainage arsenic ion sludge treatment Horobetsu mine Hokkaido Japan ferrous iron membrane filter pore size arsenite solutions microbial oxidation As Fe Manufacturing and Production  
  Abstract An acid mine drainage in abandoned Horobetsu mine in Hokkaido, Japan, contains arsenic and iron ions; total arsenic ca.10ppm, As(III) ca. 8.5ppm, total iron 379ppm, ferrous iron 266ppm, pH1.8. Arsenic occurs mostly as arsenite (As (III)) or arsenate (As (V)) in natural water. As(III) is more difficult to be remove than As(V), and it is necessary to oxidize As(III) to As(V) for effective removal. 5mL of the mine drainage or its filtrate through the membrane filter (pore size 0.45 mu m) were added to arsenite solutions (pH1.8) with the concentration of 5ppm. After the incubation of 30 days, As(III) was oxidized completely with the addition of the mine drainage while the oxidation did not occur with the addition of filtrate, indicating the microbial oxidation of As(III). In this paper, we have investigated the microbial oxidation of As(III) in acid water below pH2.0.

  Year 2002 Publication Reviews in Environmental Science & Biotechnology Abbreviated Journal  
  Volume 1 Issue 5 Pages 335-343  
  Keywords acid mine drainage acidophilic microorganisms heavy metals iron oxidation iron reduction remediation sulfate reduction wetlands Wheal Jane  
  Abstract Passive (wetland) treatment of waters draining abandoned and derelict mine sites has a number of detrac-tions. Detailed knowledge of many of the fundamental processes that dictate the performance and longevity of constructed systems is currently very limited and therefore more research effort is needed before passive treatment becomes an “off-the-shelf” technology.
