  1. 1. Structural controls on the shear zone hosted, IOCG-style Kiskamavaara Cu-Co-Au mineralization

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

    Författare :Nicolai Metzger; [2019]
    Nyckelord :;

    Sammanfattning : Sweden is the largest producer of iron ore in the European Union, as well as amongst the top producers for base and precious metals. Much of its mineral wealth derives from northern Norrbotten, type locality of the Kiruna-type-magnetite-apatite ores. LÄS MER

  3. 2. Potential Use of Oxygen Depleted Air In Nickel Sulphide Flotation

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Bianca Henriques Leal Andrade; [2018]
    Nyckelord :;

    Sammanfattning : Copper-nickel low grade ore deposits normally have complex mineralogy and process behaviour. Implementing an optimum process that is able to recover all the valuable minerals efficiently is challenging. One concentration strategy in mineral processing of copper-nickel sulphide ores is stage-wise flotation. LÄS MER

    Sammanfattning : This thesis aims to provide adequate analytical information on the spade shaped iron bars of Norrland and central Sweden. While their significance has been thoroughly debated for decades, analytical research on them has been confined to cases of single artefacts or theoretical interpretations of their value, meaning and origin.

  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

  7. 5. Ore Petrography and Geochemistry of some REE-bearing Fe-oxide Assemblages from the Idkerberget Deposit, Bergslagen, Sweden

    Kandidat-uppsats, Institutionen för geovetenskaper

    Författare :Fredrik Sahlström; [2012]
    Nyckelord :Idkerberget; Petrography; Geochemistry; REE; Apatite-Iron Oxide Ore;

    Sammanfattning : The mine dumps of Kiruna-type apatite-iron oxide ore in Bergslagen, South Central Sweden, contain elevated amounts of rare earth elements (REEs). A recently started project at Uppsala University has been initiated to study these ores among others in order to document occurrences of REEs and other critical elements in the mine dumps. LÄS MER
