  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Sequential extraction combined with isotopic analysis as a tool for studying lead contamination from mining activity

    Tailings deposits generated from mining activities constitute a potential risk to the environment through leaching of potentially toxic elements hosted by a variety of minerals present in the mine-waste materials. In the present work, in an attempt to study the potential mobility of lead in different type of Pb-Zn ore concentrate residues and its environmental impact, a sequential extraction ...

  • Generalized Calibration of a Nuclear Moisture/Density Depth Gauge

    The application of nuclear moisture/density depth gauges to soil deposits has generally relied on calibration by direct correlation with measured values of moisture content and density. In very soft variable deposits such as coal tailings, direct calibration is not possible. A generalized calibration can be developed from first principles based on the elemental composition of the soil being ...

  • 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 ...

  • Potash slope stability using SVSlope

    A project recently undertaken by students at University of Regina involved slope stability numerical modeling of potash tailings. The work involved two primary objectives: Use slope stability software to determine the factor of safety of one side of the waste pile, and Perform a sensitivity analysis to identify the safe terminal height and optimized volume that could fit within the current land ...

  • ArmorMax® Chosen in Milltown reservoir diversion channel stabilization project for state of Montana case study

    PROJECT SUMMARY Over 100 years of deposited mine tailings prompted the Montana DEQ and U.S. EPA to embark on a major initiative to breach the Milltown Reservoir Dam and clean up contaminated sediments. But maintaining the flow of the Blackfoot and Clark Fork Rivers called for a potentially expensive diversion channel. Incorporating the AR-MORMAX® ARVS in the upper cross section to protect ...

  • Métallurgie Magnola, Quebec Case Study

    Métallurgie Magnola Inc. (MMI) is a company based in Danville - Québec, Canada - specializing in the production of magnesium from mine tailings located close to the plant. In 2003 the company was forced to suspend operations because of the intense competition coming from China. Problem During MMI's production process, a residual mainly composed of silica and iron was ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Diagnostic review of Kotri drainage circle under NDP

    Pakistan is a developing country having highest population growth rate of about 3% per annum that requiring the increasing water demand year by year. The demand of water consumption can be coped with modernization of irrigation system through integrated Resources Management and support agricultural modernization for the sustainable development, socially, environmentally and economically. Pakistan ...

  • Sand Plant

    Sand Plant,Sand Processing Plant The sand plant reserve came from a old stream bed, that had a 20 to 30 ft thick sand deposit in it. It was sampled and the lab testing revealed that there was less than 0.03% iron, and a few other metals (TiO2, Al2O3, MgO). The sand plant equipment length of the deposit was over a mile, so ...
