  • 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 ...


  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Rehabilitation of Mine Tailings by Simultaneous Prevention of Oxidation and Treatment of Acid Effluents Using a Wood-Waste Cover

    At the East Sullivan site, wood wastes covering the abandoned mine tailings impoundment prevent sulfide oxidation by creating an anoxic environment. The addition of coarse ligneous wastes and their high permeability favour infiltration, resulting in a water table rise that maintains most tailings under water saturation and thus provides an additional protection against sulfide oxidation. ...

  • 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 ...

  • 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 ...


  • Application of three tailing-based composites in treating comprehensive electroplating wastewater

    Heavy metals and chemical oxygen demand (COD) are major challenging pollutants for most electroplating wastewater treatment plants. A novel composite material, prepared with a mixture of calcium and sodium compounds and tailings, was simply mixed by ratios and used to treat a comprehensive electroplating wastewater with influent COD, total copper (T-Cu), and total nickel (T-Ni) respectively as ...

  • Evolution of Disposal Cell Cover Design Used for Uranium Mill Tailings Long-Term Containment

    ABSTRACT Technology used to design protective covers overlying hazardous and low-level radioactive waste cells evolved significantly during the course of the Uranium Mill Tailings Remedial Action (UMTRA) Project. Our country's operational experience in long-term containment of hazardous and radioactive wastes has been gained primarily through efforts expended by the UMTRA Project administered ...

  • 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 ...

  • Geotube Dewatering Technology Provides An Effective Dewatering Technology Solution For Dewatering Aggregate Tailings - Case Study

    Simple and inexpensive, Geotube dewatering technology can make management of tailings and fines much easier. Many aggregate plants experience high equipment and manpower costs associated with the handling and removing o( tailings and fines from settling ponds. The costs of maintaining pond operations can vary significantly from plant to plant. Not only is valuable space tied up ...

  • Are mining waste disasters inevitable?

    On 5 November 2015 the dam of an iron ore tailings management facility in Bento Rodrigues, Brazil, suffered a catastrophic failure and flooded the area. The immediate consequences were dire: the accident killed at least 11 people, injured over a dozen more and left more than 500 people homeless. However, this is just the start: the environmental impact of the Bento Rodrigues dam disaster, with ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Wasted sales efforts (leaky funnel?)

    Sales Methodologies (Processes) Every year, it seems, there emerges some new sales philosophy or methodology. Perhaps this is part of the sales energy-renewal process: some new approach to selling, preached with the fervour of a new religion by its evangelists (consultants). Some of the popular ones include Miller Heiman, Solution Selling, Selling with Integrity, ROI Selling, PoV Selling, ...

  • A Study on the Costs of Improving the Management of Mining Waste

    1. Executive Summary Context, Scope and Priorities 1.1 This is the Final Report of a study into the costs of improving the management of mining waste. It was not carried out in isolation, but in parallel with a consultation process being run by the Directorate General for the Environment of the European Commission (DG ENV) and a technical review process coordinated by the European Integrated ...

  • Management of Mining, Quarrying and Ore-Processing Waste in the European Union

    At the request of the Environment Directorate-General of the European Commission, BRGM (Bureau de Recherches Géologiques et Minières) has conducted a study on the management of mining, quarrying and ore-processing waste in the European Union. This project was completed mainly through the use of questionnaire sent to sub- contractors in almost each country of the EU. To assess this information ...

  • Application of coupled thermostatted columns in civil engineering and for leaching heavy metals of wastes from foundry sands and mining industry

    For many years, the mining industry at Pachuca Hidalgo, Mexico, has produced silver and gold through a cyanide process. Solid wastes (tailings) of this process have been deposited close to centres of population. Many of the metals in these wastes are dispersed via wind and rain, and can be toxic to flora and fauna. Foundry sands are wastes, produced by the automotive industry, the metallurgy ...
