  4. 22. The High-Pressure Study on the Fe - O System: Thermodynamics and Phase Transitions of Iron Ferrite (FeFe2O4)

    Author : Olga Shebanova; Peter Lazor; Viktor Struzhkin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; high pressure; high temperature; thermodynamics; phase transitions; magnetite; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Knowledge about the stability of phases and their relationships in the Fe-O system at high pressures and temperatures is essential in implications of the multifarious states of iron oxides for models of the evolution of the Earth. In this respect, the iron ferrite magnetite (FeFe2O4) plays a significant role since it participates in the control of geochemistry of ferric iron, and hence oxygen fugacity in the Earth`s deep interior.

  5. 23. Adsorption of surfactants and polymers on iron oxides : implications for flotation and agglomeration of iron ore

    Author : Elisaveta Potapova; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : Iron ore pellets are an important refined product used as a raw material in the production of steel. In order to meet the requirements of the processes for iron production, the iron ore is upgraded in a number of steps including, among others, reverse flotation. READ MORE

  6. 24. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

    Author : Cecilia Lund; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. READ MORE

  7. 25. Geophysical targeting of Fe-oxide Cu-Au deposits in the northern fennoscandian sheild

    Author : Alessandro Sandrin; Satu Mertanen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics; Exploration Geophysics; Prospekteringsgeofysik;

    Abstract : In the last decades Fe-Oxide Cu-Au deposits have been discovered and developed in Australia, South America and Canada. This class of mineral deposits is also present in northern Sweden and thus represents a potential target for improving the mineral production of the country. READ MORE
