  1. 1. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :John Winlund; [2022]
    Nyckelord :backfilled tailings; Dannemora mine; iron ore; rock stability; stopes; återfylld anrikningssand; Dannemoragruvan; järnmalm; bergstabilitet; öppna brytningsrum;

    Sammanfattning : The cut-off grade determines what rock mass are economic to mine. At the Dannemora mine, in eastern Bergslagen, Sweden, previously processed ore generated tailings (enrichment sand) with an iron content of 21-22 % that was backfilled into large open bodies (stopes) in the mine between 2013-2015.

  3. 2. Decarbonising the Mining Industry: The Case of Dannemora Iron Ore Mine

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Felix Meyer; [2022]
    Nyckelord :Sustainable Energy Transition; Decarbonisation; Electrification; LCI; Mining; Iron ore; Dannemora.;

    Sammanfattning : The Swedish mining and minerals sector is one of the most prominent greenhouse gas emitters in the country. At the same time, it also provides Sweden and other nations with vast amounts of important metals and minerals, which are not easily replaced. LÄS MER

  4. 3. Induced Seismicity in the Dannemora Mine, Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Joanna Holmgren; [2015]
    Nyckelord :Mining-induced seismicity; phase picking; particle motion; local earthquake tomography; correlation; local magnitude;

    Sammanfattning : Induced seismicity is a common phenomenon that occurs as soon as the stress state in the subsurface is externally altered in a way that faults are destabilized. It is especially problematic in stable tectonic regions where the area is not used to earthquakes; the infrastructure is not built to withstand ground movement and thus when the induced seismicity occurs damage can follow.

  5. 4. Mineralogical Study of Manganese Bearing Skarn Minerals and Manganese Content in Magnetite in the Dannemora Skarn Iron Ore Deposit

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Franz Åberg; [2015]
    Nyckelord :Dannemora; ore; iron skarn; manganese; magnetite; skarn minerals; Dannemora; malm; järnskarn; mangan; magnetit; skarnmineral;

    Sammanfattning : The Dannemora skarn iron ore deposit is located in the northeastern part of Bergslagen. The deposit has been mined from the 1400’s and stopped in 1992, the mine was reopen in 2012 and it will close in 2015. The Dannemora deposit is hosted by 1.9 Ga old sedimentary and volcanic rocks.

  7. 5. Dannemora gruva : en verksamhet med lång historia och stor betydelse för det lokala samhället

    Kandidat-uppsats, Uppsala universitet/Kulturgeografiska institutionen

    Författare :Sandra Gustafsson; [2014]
    Nyckelord :Dannemora; gruvindustri; livsform; platskänsla; lokaliseringsteori;

    Sammanfattning : Den svenska järnindustrin har en många hundraårig lång tradition och järn har under stora dela av tiden varit en av landets främsta exportvaror. Järnindustrin har därför spelat en viktig roll för såväl den nationella ekonomin som för gruvorternas lokala arbetsmarknad. LÄS MER
