  • Optimising the Rehabilitation of polluted Mine Tailings and Water by SupaZorb

    To date the polluted acid mine drainage (AMD) – the second biggest environmental problem of the world - from South Africa’s gold mines, was characterised and treated by the precipitation of heavy metals with lime and sulphates, by means of iron exchange. The chemical treatment with expensive and toxic caustic soda (Sodium Hydroxide, NaOH) is to lift the pH, in order to reduce the corrosion on ...

  • Tailings paste disposal – more than water recovery

    The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. ...

  • Solving tailings impoundment water balance problems

    This application of SVFlux involved the calculation of a water balance for a tailings facility close to Queensland, Australia. Flow past the earth dams had been measured in the field and the desire was to see if a numerical model could accurately predict the flow in a blind test. The climate in the area is semi-arid with an annual rainfall of 702 mm/yr and a potential evaporation rate of 1650 ...

  • Environmental Information Systems for Tailings Management

    Introduction An EU Directive is forcing waste disposal sites, such as refuse tips and landfills, to upgrade their anti-leaching precautions. This is especially the case in Sweden. Here, in its home market, Trelleborg is able to provide these sites with an environmentally friendly, seam-weldable rubber membrane to meet the stringent new requirements. An EU Directive came is now in force ...


  • 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, ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • Seasonal variation of microbial community for the treatment of tail water in constructed wetland

    Effects of seasons and hydraulic loading rates (HLR) on the treatment performance and the response of the microbial community of vertical flow constructed wetland treating tail water were investigated. The seasonal treatment performance was evaluated at four HLR of 125, 250, 375 and 500 mm/d, respectively. The microbial community was detected by MiSeq Illumina platform at HLR 125 and 375 mm/d. ...

  • Water services in small towns in developing countries: at the tail end of development

    The current lack of knowledge about small towns, the great diversity of such settlements and the pressure to ‘scale up’ interventions make it difficult for policy makers and practitioners to develop models which are suitable for these towns. Currently, principles and practices informing models for water services in urban and rural areas are applied in small towns without question. This paper ...

  • Mineralogical constraints on the mobility of arsenic in tailings from Zimapan, Hidalgo, Mexico

    Arsenic mobility was studied in tailings from Zimapan, a mining zone of Mexico. Primary mineral phases are quartz, calcite, pyrite, pyrrhotite, sphalerite and arsenopyrite. Secondary minerals in oxidised tailings include gypsum, K-jarosite, lepidocrocite, goethite, beudantite and kaolinite. The highest levels of As (up to 3.95 ± 2.29 weight %), Zn (up to 3.26 ± 2.21 weight %) and Pb (up to 0.93 ± ...

  • Syncrude oilsands tailings pond, Ft. McMurray, Alberta, Canada - Case Study

    Syncrude Canada produces a large part of Canada's crude oil supply. The company processes about 225,000 bbl/day. The oil produced is used for jet and automobile fuel, home heating oil, plastics and other consumer synthetics. Crude oil is produced through a process of mining, extracting and upgrading bitumen. A rich supply of bitumen is contained in the Athabasca oil sands deposit in northern ...

  • Release of metals and arsenic from various mine tailings by Eriophorum angustifolium

    Abstract  Previous investigations have found that plants grown on sulphide-rich mine tailings have phytostabilising effects on acid mine drainage (AMD) by decreasing the pH and preventing the release of metals. The possibility of similar effects on tailings containing other minerals was investigated here. The aim was to examine the effects of Eriophorum angustifolium on four water-covered mine ...

  • 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 ...

  • Lab scale treatment evaluation of contaminated water from a mine tailings pond through addition of coagulants and flocculants

    Location: Colomac Mine, N.W.T. Owner: Indian and Northern Affairs Description: Tailings water from an abandoned gold mine was contaminated with Cyanide, Ammonia, Arsenic, Copper, Lead, Nickel and Zinc. Treatment evaluation involved addition of coagulants and flocculants to precipitate Cyanide, Ammonia and metals out of solution. Chemical ...

  • The feasibility of non-water reaction polymer grouting technology application in seepage prevention for tailings reservoirs

    Tailings reservoirs generally consist of a tailings dam, a tailings conveying system and a drainage system, which are indispensable facilities and provide security and environmental protection for storing tailings and clarifying water in some industries (e.g., metallurgy, non-ferrous building materials, nuclear and chemical industries). Consequently, consolidating seepage prevention and ...

  • The hidden urban tail-enders – drinking water supply as a common pool resource problem in Khorezm, Uzbekistan

    In academic debates, drinking water supply is considered mainly to be either a public or an economic good, or something in between. Nevertheless, in situations of insufficient supply, the non-academic literature refers to common pool resource problems, in which certain uses of drinking water should be 'avoided' or even 'punished'. To highlight the importance of understanding drinking water supply ...

  • Optimising the rehabilitation of polluted mine tailings and water by an organic medium passive acid mine drainage treatment in South Africa

    Up to the present polluted Acid Mine Drainage (AMD) also known as Acid Rock Drainage (ARD) from South Africa's gold mines was treated by the precipitation of heavy metals with lime and expensive caustic soda where the residues accumulate in the treated water. This water then is dispersed into wetlands for natural remediation. The environmental damage to soil is irreversible and can sterilise soil ...

  • Geotube Dewatering Technology Used To Alleviate Acid Runoff Problem from Mine Tailings - Case Study

    Construction on 1-99 in Pennsylvania unearths pyretic rock; Geotube units used to contain minerals that could contaminate groundwater. Many states are faced with the problem of dealing with tailings and residues from mining, road building, and other sources that pose a threat to groundwater. Residues can come from both old inventories of stockpiled material, as well as those materials ...

  • Investigation of contaminant transport in groundwater from the tailings pond of uranium mine: a case study

    The present study investigates the spreading of radioactive materials through groundwater by developing a groundwater contaminant transport model. The model was analysed in the steady state, and was then applied in the transient state to predict the spreading of uranium and its daughter product in the region. The model was verified using the simulated and measured velocity of groundwater. It was ...
