  • 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 pollution control regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time and money spent on protecting ...

  • On the tails of distributions of annual peak flow

    This study discusses an application of heavy-tailed distributions to modelling of annual peak flows in general and of Polish data sets in particular. One- and two-shape parameter heavy-tailed distributions are obtained by transformations of random variables. The correct selection of a flood frequency model with emphasis on heavy-tailed distribution discrimination is then discussed. If a ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Are we chasing our tail in the pursuit of sustainability?

    People are urged to change their pattern of consumption and lifestyle in a more environment-friendly direction. More eco-efficient products and production are also developed. But when governments strive to promote economic growth, consumers may be urged to consume more to cure or prevent a stagnating economy. Here is an obvious contradiction. Gains in eco-efficiency are likely to be annihilated ...

  • Tailings Dams: Risk of Dangerous Occurences - Lessons learnt from practical experiences

    This bulletin analyses the causes of 221 tailings dams accidents and failures, and offers examples of effective remedial measures. Knowledge about the factors that control the behaviour of tailings dams has improved greatly during the past 20 years as have the consequences and public perception of tailings dam failures, causing managers and owners to become more aware of the risks involved in the ...


  • 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 ...

  • Restoration of high zinc and lead tailings with municipal biosolids and lime: a field study

    Received for publication February 26, 2008. A field study was conducted to test the ability of biosolids (BS) and different types of lime to increase soil pH, neutralize subsoil acidity, and restore a vegetative cover to alluvial mine tailings in Leadville, CO. The tailings had soil pH of 5.2 and total Cd, Pb, and Zn of 75 ± 20, 2600 ± 1100, and 6700 ± 1900 mg kg–1. Types of lime included ...
