  1. 1. The Tjårrojåkka apatite-iron and Cu (-Au) deposits, northern Sweden products of one ore forming event

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Åsa Edfelt; Luleå tekniska universitet.; [2007]
    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 apatite-iron (Kiruna type) and Cu (-Au) deposits in Sweden. The results from this project show that the two deposits are genetically related and indicate the presence of a younger, previously unknown, 1780 Ma generation of apatite- iron ores in northern Sweden.

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Cecilia Lund; Luleå tekniska universitet.; [2013]
    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. 5. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining

    University dissertation from Luleå University of Technology

    Author : Mathis Warlo; Luleå tekniska universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
