  • Anglo Coal - Case Study

    Acidic mine water treatment without lime South African Coal Estates (SACE) is a division of Anglo Coal and operates the coalmine at Landau Colliery in South Africa. Processing of the coal results in a sulphate-rich effluent. Part of the sulphate is removed with lime precipitation but this produces an effluent that is oversaturated with gypsum. As a result, scaling occurred ...

  • Identification of potential sewer mining locations: a Monte-Carlo based approach

    Rapid urbanization affecting demand patterns, coupled with potential water shortages due to supply side impacts of climatic changes, has led to the emergence of new technologies for water and wastewater reuse. Sewer mining (SM) is a novel decentralized option that could potentially provide non-potable water for urban uses, including for example the irrigation of urban green spaces, providing a ...

  • Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study

    Problem At an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950's, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through ...

  • Migration and speciation of heavy metal in salinized mine tailings affected by iron mining

    The negative effects of heavy metals have aroused much attention due to their high toxicity to human beings. Migration and transformation trend of heavy metals have a close relationship with soil safety. Researching on migration and transformation of heavy metals in tailings can provide a reliable basis for pollution management and ecosystem restoration. Heavy metal speciation plays an ...

  • The drainage of lake ‘L'Estany’ in Spain

    In the 18th century, the practice of drying up the wetlands, marshy or stagnant water areas expanded throughout Europe in order to avoid the malaria fevers that the population periodically suffered and to recover land for farming. This communication describes the current knowledge about the history of the process of drying in various hydrological basins as well as the works in the endorheic ...

  • Meliadine Mine - Case Study

    This is a case study for a mine remote located in the Nothern region Nunavut of Canada. Meliadine is a gold mine where the camp wastewater is treated by a MBR technology. Probiosphere Bioremediation product Archaea supported the commissioning and startup of this project. This case study relates how Probiosphere Bacterial products can be trusted even after having gone under harsh environmental ...

  • Analysis of mine water from four decommissioned pits in south-western Ghana – implications for remediation programmes for mine closure

    Research into water quality status of accumulated water in decommissioned pits is a grey area in Ghana and could be of significant benefit in the effectiveness of remediation of pits after mining. Water sampled from four decommissioned pits in Amansie West District were analysed for their water quality status. Seasonal variations of physico-chemical parameters for determining water quality ...

  • Hydrochemical characterization of a river affected by acid mine drainage in the Iberian Pyrite Belt

    This paper addresses the modelling of the processes associated with acid mine drainage affecting the Trimpancho River basin, chosen for this purpose because of its location and paradigmatic hydrological, geological, mining and environmental contexts. By using physical-chemical indicators it is possible to define the contamination degree of the system from the perspective of an entire river ...

  • Integrated treatment of acid mine drainage using cryptocrystalline magnesite and barium chloride

    This study endeavours to report the efficiency of a hybrid approach in the treatment of acid mine drainage. Cryptocrystalline magnesite was used to pre-treat acid mine drainage and barium chloride was used to remove the residual sulphate through the formation of barium sulphate. Batch experimental approach was adopted and the documented optimum conditions for both cryptocrystalline magnesite ...

  • Passive neutralization of acid mine drainage using basic oxygen furnace slag as neutralization material: experimental and modelling

    This study investigated passive neutralization of acid mine drainage using basic oxygen furnace slag as neutralization material over 90 days, with monitoring of the parameters' quality and assessment of their removal kinetics. The quality was observed to significantly improve over time with most parameters removed from the influent during the first 10 days. In this regard, removal of acidity, ...

  • Superfund Investigates Land Pollution from the Past…and Present

    On September 7, 2016, we took steps to respond to states, tribes and citizens who asked for our help addressing contaminated sites. In response, we are adding 10 hazardous waste sites to the National Priorities List (NPL). The NPL is our list of more than 1,300 of the most contaminated sites in the country that we are addressing under the Superfund program. Superfund is one of the most important ...

  • Donald Blankenship Charged in Mine Disaster

    Former chief executive of Massey Energy Company, Donald Blankenship, was charged for multiple violations of safety rules and deceit of federal inspectors that ultimately led to the death of 29 coal miners during a single incident in 2010; the deadliest mine incident since 1970. Indicted on four criminal counts by a federal grand jury in the Upper Big Branch disaster, Blankenship faces a ...

  • Alleviation of environmental risks associated with severely contaminated mine tailings using amendments: Modeling of trace element speciation, solubility, and plant assssccumulation

    Tailings are considered one of the most relevant sources of contamination associated with mining activities. Phytostabilization of mine spoils may need the application of the adequate combination of amendments to facilitate plant establishment and reduce their environmental impact. Two pot experiments were set up to assess the capability of 2 inorganic materials (calcium carbonate and a red ...

  • Assessment of nanofiltration and reverse osmosis potentialities to recover metals, sulfuric acid, and recycled water from acid gold mining effluent

    This work assessed the potential of nanofiltration (NF) and reverse osmosis (RO) to treat acid streams contaminated with metals, such as effluent from the pressure oxidation process (POX) used in refractory gold ore processing. NF and RO were evaluated in terms of rejections of sulfuric acid and metals. Regarding NF, high sulfuric acid permeation (∼100%), was observed, while metals were ...
