  1. 1. Silver Mineralogy and Modes of Occurrence at the Silver Hart Deposit, South East Yukon.

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

    Author : Michael Ives-Ruyter; [2023]
    Keywords : Canada; Yukon; silver; lead; zinc; galena; sulfosalt; sulfur isotope;

    Abstract : The Silver Hart property is a high grade silver-lead-zinc deposit consisting of polymetallic vein style, manto (carbonate replacement) style, and skarn type mineralization. Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. READ MORE

  3. 2. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

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

    Author : Elina Fernö; [2023]
    Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

  4. 3. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Morgan Eliasson; [2023]
    Keywords : Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

    Abstract : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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.

  6. 5. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

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

    Author : Marcus Eriksson; [2020]
    Keywords : Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Abstract : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. READ MORE
