  1. 1. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Författare :Riaz Bhanbhro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Sammanfattning : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. LÄS MER

  3. 2. Mechanical Properties of Tailings : Basic Description of a Tailings Material from Sweden

    Författare :Riaz Bhanbhro; Peter Viklander; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Tailings dams are constructed to store waste material from mining industry and usually these dams are raised with time depending upon production rate. Tailings material is sometimes used in construction of tailings dams. LÄS MER

  4. 3. Geomechanical properties of tailings : a study of backfill materials for mines

    Författare :Lars Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : .... LÄS MER

  5. 4. Stability of tailings dams : focus on water cover closure

    Författare :Annika Bjelkevik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Mining activities have been ongoing for thousands of years within Sweden. As the results of previous activities are evident today, i.e. for example acid mine drainage (AMD), the focus and interest on closure and remediation of mine sites and tailings storage facilities (TSFs) has increased.

  7. 5. Phytostabilisation : use of wetland plants to treat mine tailings

    Författare :Eva Stoltz; Maria Greger; Lena Kautsky; Marinus Otte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytostabilisation; wetland plants; mine tailings; Plant physiology; Växtfysiologi;

    Sammanfattning : Mine tailings can be rich in sulphide minerals and may form acid mine drainage (AMD) through reaction with atmospheric oxygen and water. AMD contains elevated levels of metals and arsenic (As) that could be harmful to animals and plants. LÄS MER
