  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • VSEP filters mine tailing pond effluent with no pre-treatment required

    New Logic International installed its Vibratory Shear Enhanced Processing (VSEP) system in March, 1998 at a major California rare earth mining and manufacturing facility. The VSEP is used for treatment of mine tailing pond effluent at this facility with no pretreatment required. The VSEP system uses nanofiltration followed by ultrafiltration membrane modules and is able to treat the mine tailing ...

  • 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 ...

  • Mine backfill

    Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

  • Quantitative microbial community analysis of three different sulfidic mine tailing dumps generating acid mine drainage

    The microbial communities of three different sulfidic and acidic mine waste tailing dumps located in Botswana, Germany, and Sweden were quantitatively analyzed using quantitative real-time PCR (Q-PCR), fluorescence in situ hybridization (FISH), catalyzed reporter deposition-FISH (CARD-FISH), Sybr green II direct counting, and the most probable ...

  • Establishment and growth of two willow species in a Riparian zone impacted by mine tailings

    Received for publication April 2, 2008. A field study was initiated to determine survival, growth characteristics, and metal uptake of two montane riparian willow species, Geyer (Salix geyeriana Andersson) and mountain (S. monticola Bebb) willow, grown in amended fluvial mine tailing deposits. Revegetation was done with staked and previously rooted cuttings to determine if planting method had an ...

  • 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 ...

  • 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 ...

  • Case study - tailing ponds

    Location: Canada Year: 2012 Working context Oil Sand - Tailing pond dredging - The standard industry practice is to pump oil sands tailings into large settling ponds. There, the heaviest material settles to the bottom, separating from the top layer of water which can be recycled. The problem Oil ...

  • Suitability of Wastes from Olive-Oil Industry for Initial Reclamation of a Pb/Zn Mine Tailing

    An incubation experiment was conducted to evaluate the ameliorating role of two organic amendments—olive-mill solid wastes and compost from olive-mill solid wastes- in the ecological reclamation of a lead/Zn-mine tailing collected in southern Spain. Four enzymatic activities (dehydrogenase, β,-glucosidase, urease and phosphatase) and soluble and AB-DTPA extractable Pb and Zn and were ...
