  1. 1. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE

  3. 2. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Magnus Kemi; [2023]
    Keywords : bio-energy; biomass; coal; greenhouse gas emissions; industrial residues; LCA; LKAB; logging residues; iron ore; pellets; sinters; willow; sustainability;

    Abstract : Iron production accounts for substantial shares of global coal use and GHG emissions. LKAB is Europe’s largest iron company and Sweden’s fourth-largest emitter of GHGs. To reduce its emissions, LKAB might implement biomass in iron ore pelletisation. READ MORE

  4. 3. Residual Products in the Steel Industry Used for Briquetting

    University essay from KTH/Materialvetenskap

    Author : Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
    Keywords : ;

    Abstract : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. READ MORE

  5. 4. 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

  6. 5. Mining for Whose Future? The Recycling of Narratives for Continuous Extraction : A discursive study of the Gállok mine

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Engström; [2023]
    Keywords : Environmental Justice; Sámi rights; Gállok; Critical Discourse Analysis; Green growth; Green transition; Mining;

    Abstract : The Exploitation of land for economic growth has been an ongoing issue for locals’ rights to land, especially indigenous people. In Sweden, EU’s largest producer of Iron ore, the conflict between the State, indigenous Sámi, and mining industries have caused many controversies over the years, where mining projects repeatedly infringe upon land inhabited by Sámi.
