  • 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, ...

  • 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 ...

  • Why is mining wastewater treatment necessary?

    During Industrial processes and mining, there are certain discharges of environmental pollution. This outcome is the growing concerns about the living atmosphere. As per the increasing concerns of contamination, there should be a lot of efforts and implementation to save the environment from its hazardous ...

  • A new and effective approach to boron removal by using novel boron-specific fungi isolated from boron mining wastewater

    Boron-resistant fungi were isolated from the wastewater of a boron mine in Turkey. Boron removal efficiencies of Penicillium crustosum and Rhodotorula mucilaginosa were detected in different media compositions. Minimal Salt Medium (MSM) and two different waste media containing molasses (WM-1) or whey + molasses (WM-2) were tested to make this process cost effective when ...

  • Investigating the permeability of fractured rock masses and the origin of water in a mine tunnel in Shandong Province, China

    The coastal Sanshandao mine is threatened by the overlying Quaternary water and seawater. Following an introduction to the geology and hydrogeological conditions in the mine area, a detailed hydrogeological survey and sampling were conducted and hydrochemical and stable isotopic (δ2H and δ18O) tests on various waters were carried out to characterize the origin of water in the mine ...

  • Mining wastewater management and its effects on groundwater and ecosystems

    Large-scale mining activities have a huge impact on the environment. Determination of the size of the effect and monitoring it is vital. In this study, risk assessment studies in mining areas and the effect of mining on groundwater and ecosystems were investigated. Best management practices and risk assessment steps were determined, especially in areas with huge amounts of mining wastewater. The ...

  • Treatment of iron(II)-rich acid mine water with limestone and oxygen

    The main components of acid mine water are free acid, sulphate, and Fe2+. Limestone is the most cost-effective alkali that can be used for neutralization. The purpose of this investigation was to identify conditions where Fe2+ is removed with limestone and simultaneously oxidized with oxygen to Fe3+, in a polyvinyl chloride pipe under pressure. Gypsum ...

  • Root length of aquatic plant, Lemna minor L., as an optimal toxicity endpoint for bio‐monitoring of mining effluents

    Lemna minor, a free‐floating macrophyte, is used for bio‐monitoring of mine effluent quality under the Metal Mining Effluent Regulations (MMER) of the Environmental Effects Monitoring (EEM) program in Canada, and is known to be sensitive to trace metals commonly discharged in mine effluents such as nickel. Environment Canada's standard toxicity testing protocol recommends frond count (FC) and ...

  • Phosphate Mine Tailings - Case Study

    THE CHALLENGE A typical phosphate mining operation can produce between 180,000 and 225,000 gallons per minute of fine phosphatic clay tailings. This material has a solids concentration of between 2% and 7% on a dry-solids basis. Currently, ponds and lagoons are used for settling and clarification of these materials. Many of these polishing ponds are approximately 200 to 300 acres in size, ...

  • Mining Water Quality Application

    Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). One of the environmental monitoring requirements which must be met is monitoring water. These include potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The ...

  • Expression of immunoregulatory genes and its relationship to lead exposure and lead‐mediated oxidative stress in wild ungulates from an abandoned mining area

    Lead (Pb) is a highly toxic metal that can induce oxidative stress and affect the immune system by modifying the expression of immunomodulator‐related genes. The aim of the present study was to investigate the association between Pb exposure and the transcriptional profiles of some cytokines, as well as the relationship between Pb exposure and changes in oxidative stress biomarkers observed in ...

  • Well-Field Mechanics for In-Situ Mining

    Over the last several decades in-situ leach mining has become increasingly popular. Conventional mining produces tailings, runoff, and considerable land disturbance—all requiring significant rehabilitation. With in-situ leach mining methods (see diagram below), disturbance is reduced because only multiple boreholes are drilled for recovery. Rehabilitation is much simpler, consequently, the ...

  • Contaminated Water

    Treatment of Contaminated Mine Water Discharge Recent estimates have suggested that in the UK 2,500 km of streams and an area of 9,000 km2 of groundwater bodies are at risk of failure of Water Framework Directive Objectives due to mine water pollution (Jarvis & Rees 2004). For over two decades the Loughor Estuary in South Wales, which carries SSSI status, had been ...

  • Visualisation of the characteristics of mining subsidence with the consideration of topography: a case study in China

    The existing three-dimensional visualisation of mining subsidence cannot fully convey the original landscape in the mining area. By using GIS and coupling the predicted result of subsidence in different mining stages with the original elevation data, a dynamic visualisation of mining process is approached, which could reflect geomorphologic features clearly. Furthermore, it visually shows the ...

  • Options for Reclamation of Mine Tailings in West Africa

    Revegetation of tailings in West Africa presents two major problems when using established methodologies, in that soils have the potential to be highly alkaline, rather than acidic, plus the majority of recommended plant species are non-native to the area.  Alteration of cap engineering however can modify hydrology, pH and morphology, allowing for a variety of habitats.  Cover crops are ...
