  1. 1. 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

  3. 2. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Dino Leopardi; [2020]
    Nyckelord :Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Sammanfattning : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. LÄS MER

  4. 3. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

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

    Författare :Filip Ivarsson; [2019]
    Nyckelord :Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Sammanfattning : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. LÄS MER

  5. 4. Initial evaluation of briquetting possibilities of CaO-containing paper production waste : For use in metallurgical processes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Wei Xia; [2018]
    Nyckelord :Waste; Metallurgical Process; Briquetting; Drop Test; Sulphide Capacity;

    Sammanfattning : Paper and pulp industry and steel industry are two major industries in Sweden, both of which are facing big challenges to treat their waste products properly. In this thesis work, initial evaluation of mechanical properties of briquettes made of waste products was performed. LÄS MER
