Deposition of mine tailings

  • Thickened Tailings Deposition for Closure

    modifying the deposition strategy so that thickened tailings are disposed in targeted areas in the latter stages of the mine life, as opposed to uncontrolled deposition for the simple purpose of filling the basin. The strategic deposition of tailings (from both central and perimeter locations) can lead to considerable cost

  • (PDF) Methods for the disposal and storage of mine tailings

    Jun 08, 2020 Figure 2 shows tailings deposition from a gold mine. in the early 1900s in the Cortez Hills, Nevada, USA. The tailings have been deposited as a slurry from the

  • Project > Non-segregating tailings deposition study

    When Canadian Natural assessed the viability of non-segregating tailings (NST) as their primary fine tailings management strategy for complying with Alberta’s oil sands tailings reclamation requirements, they turned to Barr and the Dutch firm Deltares to plan and implement a NST deposition study

  • Deposition techniques | Sustainability | Gold Fields

    Tailings deposition using the CTD method occurs by radial discharge from a fixed central discharge tower or a set number of spigots located within the central area of the TSF. The discharge point(s) is progressively raised as the elevation of the tailings increases

    and water management. This paper discusses tailings deposition control and water management methods that have been successfully used at a number of high-density tailings facilities with special reference made to central cone deposition in the Kidd Metallurgical Site and perimeter deposition at the Musselwhite Mine


    tailings are made before tailings deposition even begins – especially the tailings technology and the location and form of the tailings landform. damage the reclamation below. Currently, most mines have a ‘conceptual closure plan’ that details what needs to be done for the mine site (landscape scale) and for each mining landform (such

  • Technical Report: Design and Evaluation of Tailings

    tailings in impoundments or free-standing piles, backfilling underground mine workings and open-pits, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments. Modern tailings impoundments are engineered structures for permanently disposing of the fine-grained waste from mining and milling operations

    production rates, conventional tailings deposition remains the only proven technology at mines with high production rates. • Project economics: mine operators must weigh the tradeoffs that come with using an ATD method: a reduced footprint and less water used come at the expense of higher initial capital. While operating

  • (PDF) Investigation Of The Use Of Mine Tailings For

    Research on mine tailings stems from the necessity to prevent the danger posed by mine tailings to the environment. This danger is characterized by the tendency of mine tailings to release acids and heavy metals once in contact with oxygen and water, (Gautam et al. 2000)

  • Mine Tailings Deposition Practices, Liquefaction Potential

    SY.NOPSXS: Typical mine tailings characteristics resulting from different deposition practices are discussed. The potential for liquefaction of the tailings during seismic events is presented. A discussion of how the tailings deposition method can affect the liquefaction potential is included

  • Mine Tailings - an overview | ScienceDirect Topics

    Jan 25, 2019 At a modern mine in Papua New Guinea, 240 10 6 Mg of tailings were deposited within 10 km of the mill outfall in the Kawerrong-Jaba River system from the active Panguna copper mine on Bougainville Island (Archer et al., 1988; Jeffery et al., 1988)

  • Windblown Dust Deposition Forecasting and Spread

    The lack of vegetation and the vertical protrusion of the mine tailings above the neighboring terrain make the tailings susceptible to wind erosion. Modeling the erosion, transport and deposition of particulate matter from mine tailings is a challenge for many reasons, including heterogeneity of the soil surface, vegetative canopy coverage, dynamic meteorological

The specific field site we use for this research is the Iron King Mine tailings impoundment located in Dewey-Humboldt Arizona about 90 miles north of Phoenix. The abandoned mining operation has been classified as a Superfund site by the US EPA since 2008 (2)

  • Tailing Disposal - an overview | ScienceDirect Topics

    The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF. The tailings may be discharged from a single pipe outlet or from a number of reduced diameter spigots off the main perimeter pipeline
