  2. 6. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 8. Geology, alterations and mineral chemistry of the Tjårrojåkka Fe-oxide Cu-Au occurrences, northern Sweden

    Author : Åsa Edfelt; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related Fe-oxide Cu-Au occurrences (the Tjårrojåkka-Fe and Tjårrojåkka-Cu). The bedrock, depositional environment and tectonic evolution of the area were studied through petrological, geochemical and geophysical-petrophysical investigations. READ MORE

  6. 9. On the origin and evolution of the palaeoproterozoic Aitik Cu-Au-Ag deposit, northern Sweden : a porphyry copper-gold ore, modified by multistage metamorphic-deformational, magmatic-hydrothermal, and IOCG-mineralizing events

    Author : Christina Wanhainen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Aitik Cu-Au-Ag mine in the Gällivare area in northern Sweden is the biggest open pit operation in northern Europe and one of Europe’s largest metal producers. The open pit is almost 3 km long, 930 m wide and 345 m deep. Approximately 424 million tonnes of ore averaging 0.4% Cu, 0. READ MORE

  7. 10. 3D structural framework and constraints on the timing of hydrothermal alteration and ore formation at the Falun Zn-Pb-Cu-(Au-Ag) sulphide deposit, Bergslagen, Sweden

    Author : Tobias Christoph Kampmann; Pietari Skyttä; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Falun pyritic Zn-Pb-Cu-(Au-Ag) sulphide deposit, situated in the Palaeoproterozoic (1.9–1.8 Ga) Bergslagen lithotectonic unit in the south-western part of the Fennoscandian Shield, is one of the major base and minor precious metal sulphide deposits in Sweden. READ MORE
