  1. 6. Mineralogical, chemical and textural characterisation of the Malmberget iron ore deposit for a geometallurgical model

    Författare :Cecilia Lund; Terje Malvik; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The northern Norrbotten ore province is an intensely mineralised area and has traditionally been a very important mining district. It contains Fe, Cu-Au, Au, and Ag deposits ranging from world-class ore deposits to small and uneconomic ones (Martinsson 2004). The most important are the Kiruna and Malmberget iron ores and the Aitik Cu-Au deposit. LÄS MER

  3. 7. Mineralogical Controls on the Recovery of Antimony in Base-Metal Flotation – Outlining the Framework of a Geometallurgical Model for the Rockliden VHMS Deposit, Sweden

    Författare :Friederike Minz; Julie Hunt; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The results presented in this thesis are a case study on the polymetallic Zn–Cu volcanic-hosted massive sulphide (VHMS) deposit at Rockliden. The Rockliden mineralisation is located in north-central Sweden, about 150 km south of the Skellefte district. LÄS MER

  4. 8. Geometallurgical programs – critical evaluation of applied methods and techniques

    Författare :Viktor Lishchuk; Simon Michaux; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Geometallurgy is a team-based multidisciplinary approach aimed at integrating geological, mineralogical and metallurgical information and yielding a spatial quantitative predictive model for production management. Production management includes forecast, control and optimization of the product quality (concentrates and tailings) and metallurgical performance (e. LÄS MER

  5. 9. From minerals to trees: Reducing uncertainty in estimating weathering rates for sustainable forest growth

    Författare :Sophie Casetou; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Sustainable forest growth is fundamentally dependent on long-term supply of nutrients from mineral dissolution. Over the past century, losses of base cations (Ca, K, Mg, Na) from forest soils have been accelerated through increased forest production and anthropogenic acidification. LÄS MER

  7. 10. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining

    Författare :Mathis Warlo; Christina Wanhainen; Glenn Bark; Alan Butcher; Thomas Riegler; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ore Geology; Malmgeologi;

    Sammanfattning : Sustainable mining, including the utilisation of an ore body to its full potential, is becoming increasingly important for human society as the demand for metals increases. In order to maximise the recovery of useful metals, detailed characterisation of the ore prior to processing is vital. LÄS MER
