    Sammanfattning : Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. LÄS MER

  5. 4. Determination of dry density in tailings with a Dynamic Cone Penetrometer :

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Patrik Hagström; [2017]
    Nyckelord :dynamic cone penetrometer; tailings dam; tailings beach; tailings;

    Sammanfattning : Today mines produce metals which are used for everyday products by people worldwide. When metals are produced, waste products known as tailings are generated. These tailings are commonly stored in impoundments, surrounded by embankment dams. The demands from the society are constantly increasing regarding the quality and safety of dams. LÄS MER

  7. 5. Closure of Lilla Bredsjön Tailings Dam : an Evaluation of the Long-Term Dam Safety Measures

    Master-uppsats, KTH/Vattendragsteknik

    Författare :Jenny Bramsäter; [2017]
    Nyckelord :tailings dams; seepage; pore pressure; slope stability; slip surfaces; long-term stability;

    Sammanfattning : The mining industry contributes to enormous amounts of waste all over the world, which places high demands on tailings dams. In Sweden, there are strict regulations regarding the management and treatment of tailings dams, but some dams that were built before these regulations existed still pose a threat to the environment.
