1. 1. 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

3. 2. A literature study on measurement methods for calculating the FeO activity in slag

   University essay from KTH/Materialvetenskap

   Author : Rebecca Rosén; [2020]
   Keywords : ;

   Abstract : During the time we live in, climate change is more important than ever. HYBRIT, formed bySSAB, LKAB, and Vattenfall, is an initiative set out to make the steel production fossil free, by developing a novel process that produce direct reduced iron (DRI) using hydrogen as reagent. Electric arc furnaces (EAF) will then be employed to melt the DRI. READ MORE

4. 3. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

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

   Author : Tom Turner; [2020]
   Keywords : Bronäs; Sala;

   Abstract : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

5. 4. Observing phase changes in real time on ultrathin Iron oxide surfaces

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Harald Wallander; [2019]
   Keywords : CO oxidation; platinum; iron oxides; Physics and Astronomy;

   Abstract : Studying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar.

6. 5. The effect of carbonaceous iron on slag foaming

   University essay from KTH/Materialvetenskap

   Author : Josefin Svensson; [2018]
   Keywords : ;

   Abstract : The practise of slag foaming has become increasingly important within the scrap-based steelmaking, conducted in the electric arc furnace, due to its many advantages. In addition to increasing the efficiency in the furnace, the foaming protects the furnace equipment from wear and reduces noise pollution. READ MORE
