Title Post closure management of the Mt Leyshon Gold Mine – Water the integrator Type Journal Article
Year 2006 Publication Water in Mining 2006, Proceedings Abbreviated Journal
Volume Issue Pages 233-242
Keywords (up) mine water treatment
Abstract Mining at the Mt Leyshon Gold Mine in semi-arid north Queensland stopped in 2002. Newmont Australia has recently initiated a thorough post-closure water management study of the site by revisiting the existing information and conducting new water-related investigations. The focus of this paper. which is the first publication on post-closure environmental management of the site. is an overview of the site water quality in view of the sources and spatial distribution of polluted mine water, and also the performance of cover systems in controlling water flux though mine wastes.

Title Tracer tests as a mean of remediation procedures in mines Type Journal Article
Year 2006 Publication Uranium in the Environment: Mining Impact and Consequences Abbreviated Journal
Volume Issue Pages 817-822
Keywords (up) mine water treatment
Abstract Mining usually causes severe anthropogenic changes by which the ground- or surface water might be significantly polluted. One of the main problems in the mining industry are acid mine drainage, the drainage of heavy metals, and the prediction of mine water rebound after mine closure. Consequently, the knowledge about the hydraulic behaviour of the mine water within a flooded mine might significantly reduce the costs of mine closure and remediation. In the literature, the difficulties in evaluating the hydrodynamics of flooded mines are well described, although only few tracer tests in flooded mines have been published so far. Most tracer tests linked to mine water problems were related to either pollution of the aquifer or radioactive waste disposal and not the mine water itself.

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 373-381
Keywords (up) 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 Bioremediation method could cut cost of treating acid rock drainage Type Journal Article
Year 2006 Publication Civil Engineering Abbreviated Journal
Volume 76 Issue 7 Pages 30-31
Keywords (up) Pollution and waste management non radioactive geological abstracts: environmental geology (72 14 2) bioremediation cost benefit analysis water treatment acid mine drainage pollutant removal lake water heavy metal Lawrence County South Dakota South Dakota United States North America
Abstract The Gilt Edge Mine in South Dakota's Lawrence County was a gold mine that was abandoned later when its recent owner went bankrupt. Seeking a cost-effective method for treating millions of gallons of acid rock drainage (ARD), CDM partnered with Green World Science, Inc. (GWS) of Boise, Idaho, for the development of an in situ bioremediation process that can be used to remove metals from pit lake water. Recent testing revealed that the in situ bioremediation method can successfully remove metals from highly acidic water without the need to construct costly water treatment facilities.

Title 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 (up) 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.
