  1. 1. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Adrian Larsson; [2022]
    Nyckelord :Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

    Sammanfattning : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. LÄS MER

  3. 2. Medium term planning with Evolution : Comparison with current method at LKAB Svappavaara

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

    Författare :Koen Vos; [2018]
    Nyckelord :mining; production scheduling; mine planning;

    Sammanfattning : This thesis looks at the medium term mine planning process and tools in the Leveäniemi open pit mine operated by LKAB Svappavaara. The current planning process uses software, Chronos, which was previously used successfully to perform medium term planning for the Gruvberget mine, which is also operated by LKAB Svappavaara.

  4. 3. Particle tracking in geometallurgical testing for Leveäniemi Iron ore, Sweden

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Efraín Cárdenas; [2017]
    Nyckelord :Geometallurgy; Process mineralogy; Particle tracking; Leveäniemi; Mass balance; Iron ore; HSC;

    Sammanfattning : In a particle based geometallurgical model, the behavior of the particles can be used for forecast the products and quantify the performance of the different ore types within a deposit. The particle tracking is an algorithm developed by Lamberg and Vianna 2007 whose aim is to balance the liberation data in a mineral processing circuit composed by several processing units. LÄS MER

  5. 4. A Geometallurgical Forecast Modelfor Predicting Concentrate Quality in WLIMS Process for Leveäniemi Ore

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Kartikay Singh; [2017]
    Nyckelord :Mineral processing; geometallurgy; modelling; Davis Tube; WLIMS; LKAB; Leveäniemi;

    Sammanfattning : Previous studies have suggested that Davis tube (DT) experiment can used to study wet low intensitymagnetic separation (WLIMS) for magnetic iron ores. But DT process has never been used to mapWLIMS process, specifically in a geometallurgical framework. LÄS MER
