  2. 21. Green liquor dregs-amended till to cover sulfidic mine waste

    Author : Susanne Nigéus; Christian Maurice; Thomas Pabst; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Abstract : The mining industry produces massive amounts of waste that without treatment and in contact with oxygen can result in acid rock drainage (ARD) and increased leaching of metals. In Sweden, the common way to manage the mine waste after closure is to apply a dry coverage on top of the waste deposition. READ MORE

  4. 22. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes

    Author : Nathalie Pérez Rodríguez; Magnus Land; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cu and Fe isotopes; fractionation; tailings; plants; phytoremediation; organic amendments; soil bacteria; Cu and Fe cycle; covellite; redox processes; Applied Geology; Tillämpad geologi;

    Abstract : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. READ MORE

  5. 23. Phytostabilization of mine tailings covered with fly ash and sewage sludge

    Author : Clara Neuschütz; Maria Greger; Lena Kautsky; Anthony R. Dexter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ammonium; biosolids; cadmium; copper; energy crop; metal and nutrient leakage; nitrate; phosphate; phytoremediation; plant stress response; root exudates; zinc; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Establishing plant communities is essential for the restoration of contaminated land. As potential cover materials, fly ash and sewage sludge can prevent formation of acid mine drainage from sulfidic mine waste. READ MORE

  6. 24. Green liquor dregs as sealing layer material to cover sulphidic mine waste deposits

    Author : Maria Mäkitalo; Josef Mácsik; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Waste rock and tailings generated by sulphide ore mining often contains large amounts of iron sulphides which oxidize when exposed to atmospheric oxygen and may generate acidity. In the absence of alkaline minerals to neutralize this acidity, elements including harmful heavy metals become mobile. READ MORE

  7. 25. Effectiveness of reclamation by backfilling and sealing at Kimheden open-pit mine, northern Sweden

    Author : Lucile Villain; Erik Carlsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Reclamation of mine sites is a very recent concept on the scale of mining history. It involves the prevention or mitigation of the environmental impacts from mining, and the establishment of sustainable post-mining uses of the land. READ MORE
