  Title In situ treatment of mine waters by means of a permeable barrier Type Journal Article
  Year 2000 Publication Groundwater 2000 Abbreviated Journal  
  Volume Issue Pages (down) 417-418  
  Keywords mine water treatment  
  Abstract Acid ground waters contaminated with radioactive elements (U, Ra, Th), toxic heavy metals (Cu, Zn, Cd, Mn, Fe), arsenic and sulphates were treated by means of a permeable barrier. The barrier was filled with a mixture of biodegradable solid organic substrates (spent mushroom compost, sawdust and cow manure) and was inhabited by a mixed microbial community consisting of sulphate-reducing bacteria and other metabolically interdependent microorganisms. An efficient removal of the pollutants was achieved by this barrier during the different climatic seasons, even at ambient temperatures close to degrees C. The microbial dissimilatory sulphate reduction and the sorption of pollutants by the organic matter in the barrier were the main processes involved in this removal.

  Title Use of a wetland system for treating Pb/Zn mine effluent: A case study in southern China from 1984 to 2002 Type Journal Article
  Year 2004 Publication Wetlands Ecosystems in Asia: Function and Management Abbreviated Journal  
  Volume 1 Issue Pages (down) 413-434  
  Keywords mine water treatment  
  Abstract A constructed wetland system in Guangdong Province, South of China has been used for treating Pb/Zn mine discharge since 1984. In this chapter, the performance of this system in the purification of mine discharge, metal accumulation in different ecological compartments and ecological succession within the system during the period of 1984-2002 has been reviewed. The data show that the wetland system not only effectively remove metals (mainly Pb, Zn, Cd and Cu) and total suspended solids from the mine discharge over a long period leading to significant improvement in water quality, but also gradually increase diversity and abundance of living organisms.

  Title Changes in dissolved and total Fe and Mn in a young constructed wetland: Implications for retention performance Type Journal Article
  Year 2001 Publication Ecological Engineering Abbreviated Journal  
  Volume 17 Issue 4 Pages (down) 373-384  
  Keywords mine water treatment  
  Abstract Surface-flow wetlands are generally considered sinks for Fe and Mn but they may also export and affect the partitioning of these metals. This study was undertaken to evaluate the effect of a young constructed wetland on the retention and transformation of both dissolved and particulate Fe and Mn. Duplicate water samples were collected every three days at the inlet and outlet structures of the Monahan Wetland, Kanata, Ontario, from spring of 1997 to 1999. While on a yearly basis the wetland showed significant retention of che dissolved phase, the retention of total Fe and Mn was poor. There were strong seasonal differences in retention and, during the winter, the wetland was a source. The wetland transformed dissolved into particulate Fe and Mn from spring to fall whereas during the winter, dissolved Fe and Mn were released. Changes in pH, alkalinity and temperature could explain 11% and 40% of the outlet variation in the ratio of dissolved to total Fe and Mn respectively. Furthermore, from spring to late summer, planktonic algal biomass was negatively related to the ratio of dissolved to total Fe and Mn implying a role in Fe and Mn transformations in young wetlands where emergent and submerged vegetation have yet to dominate the system.

  Title 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 (down) 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.

  Title Wastewater recycling and environmental constraints at a base metal mine and process facilities Type Journal Article
  Year 1996 Publication Water Sci. Technol. Abbreviated Journal  
  Volume 33 Issue 10-11 Pages (down) 371-379  
  Keywords mine water treatment  
  Abstract In temperate areas of abundant freshwater there is seldom an urgency to recycle. The statutory protection of inland waters for beneficial uses such as drinking, food processing and game fishing is requiring industries to choose recycling. A European success in this trend is a base metal mining/milling industry which, since 1977, is implementing hydraulic, hydrological, treatment and ecological studies with wastewaters and mine tailings. A model activity, located 50 km from Dublin is considered. Zinc and lead concentrates produced and exported to smelters ultimately yield approximately 194,000 t and 54,000 t of these respective metals (32 and 21 percent of European production). Water use as originally planned would have been approximately 6m(3)/t of ore milled. While ore milling increased by 25 percent to 8,500t/d in 1993, water use declined by 33 percent to 4m(3)/t. The components making up this reduction range from milling technology efficiency to greater recycling from the 165 ha tailings pond. Environmental standards, based on framework regulations originating in EU Directives, have been instrumental in achieving wastewater savings. A conclusion is the value of integrating water quantity, quality, recycling, storage, production and other factors early in project planning. Copyright (C) 1996 IAWQ.
