    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alena Niarezka; [2023]
    Nyckelord :Ertelien Ni-Cu deposit; ore geology; enrichment processes; nickel; cobalt; copper; optical microscopy; electron probe micro-analysis; critical metals; Ertelien Ni-Cu fyndighet; malmgeologi; anrikningsprocesser; nickel; kobolt; koppar; optisk mikroskopi; elektronsondsmikroanalys; kritiska metaller;

    Sammanfattning : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. LÄS MER

  3. 2. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Pieslinger; [2023]
    Nyckelord :ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

    Sammanfattning : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. LÄS MER

  4. 3. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :CELESTINE IFEANYI UGWUOKE; [2023]
    Nyckelord :Tailings; Sequential extraction; Mineralogy; Sulphate;

    Sammanfattning : This research project investigated the high concentration of sulphate in a tailing pond at LKAB and the characteristics and behavior of sulphate minerals in different areas of the pond. The sampling of the tailings was carried out at Nine stationary sampling points. LÄS MER

  5. 4. Characterization of the cobalt content in zinc ore from Zinkgruvan, Sweden

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

    Författare :Ingeborg Hjorth; [2022]
    Nyckelord :Zinkgruvan; Bergslagen; Cobalt; Sphalerite; Pyrrhotite; Safflorite;

    Sammanfattning : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. LÄS MER

  7. 5. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ida Sundblom; [2022]
    Nyckelord :sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Sammanfattning : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. LÄS MER
