  2. 1. Tailings Dam Performance : Modeling and Safety Analysis of a Tailings dam

    Author : Roger Knutsson; Annika Bjelkevik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Storage and management of mine waste are both needed in the mining industry. After mineral extraction of the ore, there are generally leftovers with insufficient economical value that need to be taken care of. The finest grained fractions are referred to as tailings. READ MORE

  4. 2. Phytostabilisation : use of wetland plants to treat mine tailings

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

    Abstract : 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. READ MORE

  5. 3. Geochemical processes in sulphidic mine tailings : field and laboratory studies performed in northern Sweden at the Laver, Stekenjokk and Kristineberg mine-sites

    Author : Henning Holmström; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : This thesis presents geochemical, mineralogical and laboratory studies of unremediated and remediated tailings at two abandoned mine sites; at Laver and Stekenjokk and at one active mine site; the Kristineberg mine. At Laver the Cu released from oxidation is enriched in an enrichment zone just below the oxidation front. READ MORE

  6. 4. Mechanical Properties of Tailings : Basic Description of a Tailings Material from Sweden

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

    Abstract : 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. READ MORE

  7. 5. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

    Author : Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; Earth sciences; Geovetenskap;

    Abstract : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. READ MORE
