  1. 1. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ellen Svens; [2024]
    Keywords : Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Abstract : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

  3. 2. Investigating the effect of grinding method on ore beneficiation behaviour

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Mellisa Tanaka Mundida; [2023]
    Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Abstract : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. READ MORE

  4. 3. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  6. 5. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : CELESTINE IFEANYI UGWUOKE; [2023]
    Keywords : Tailings; Sequential extraction; Mineralogy; Sulphate;

    Abstract : 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. READ MORE
