  • 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 ...

  • Acid production potentials of massive sulfide minerals and lead–zinc mine tailings: a medium-term study

    Weathering of sulfide minerals is a principal source of acid generation. To determine acid-forming potentials of sulfide-bearing materials, two basic approaches named static and kinetic tests are available. Static tests are short-term, and easily undertaken within a few days and in a laboratory. In contrast, kinetic tests are long-term procedures and mostly carried out on site. In this study, ...

  • 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 ...

  • Governance and socio-political issues in management of acid mine drainage in South Africa

    The water resources in South Africa are threatened by current and past mining practices such as abandoned and closed mines. While mining is considered valuable for its contribution to this country's gross domestic product, its polluting effects on water and land resources have been criticised as unsustainable. Acid mine drainage (AMD) is one specific public health and ecological issue that has ...

  • 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 ...

  • How to choose the best Industrial Water Filtration System for mining applications

    Over the course of the past few decades concern for the environment has brought about a large number of new regulations concerning the use of water in mining operations. These include how it is accessed, and how it is treated, using industrial water filtration to ensure all ...

  • 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 ...

  • Mining wastewater treatment: An overall guide and introduction

    The intensity of wastewater in mining and commercial applications is huge. Because of the use of a large amount of water, most of the mining and commercial firms produce and discharge a huge quantity of wastewater which later triggers pollution and containment in the environment. However, after witnessing the harsh consequences of wastewater in both ecology and mining sectors, the government has ...

  • Everything you need to know about mining wastewater treatment

    Over the years, the mining and industrial areas have kept on occupying more remote locations, and because of this, the intensity and level of metals-loaded wastewater are raising gradually. The mounting levels of wastewater discharged from mining sectors are playing a pivotal role in environmental pollution’s and hence has become a key concern for the ecologists. To address such serious ...

  • 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 ...
