  2. 6. Competitive strength in iron ore production

    Author : Stefan Hellmer; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This thesis is about competitive strength in the global markets for iron ore. Its focus is on the Swedish iron ore producer, LKAB, and its role in this global market. The finding of new vast deposits of iron ore in Brazil and Australia, together with falling transportation costs, meant that LKAB started to meet fierce competition in the 1970s. READ MORE

  4. 7. Cost-benefit analysis of labor market programs : Applied to a temporary program in northern Sweden

    Author : Henry Ohlsson; Karl-Gustaf Löfgren; Eskil Wadensjö; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : The study's objective is to evaluate the relief works and special projects that were in effect during the period 1983-1986 due to the labor force reduction of almost 2 000 persons at the LKAB Mining Company in 1983. These reductions caused the Swedish Parliament to set up a special labor market policy organi­zation, the Malmfältsdelegation, which besides initiating relief works and spe­cial projects also functioned as an employment exchange, an employability assessment center, and a training organizer.

  5. 8. Traceability in continuous processes : applied to ore refinement processes

    Author : Björn Kvarnström; Josse De Baerdemaeker; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Abstract : Introduction and purpose: Traceability is central for the identification of the root cause(s) behind a product deviation and thus to achieve a product and process quality that is both high and even. Continuous processes contain several characteristics complicating traceability which are not usually discussed in the scientific literature. READ MORE

  6. 9. An Investigation of the Iron-Ore Wheel Damages using Vehicle Dynamics Simulation

    Author : Saeed Hossein Nia; Sebastian Stichel; Matti Rantatalo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-piece bogie; wear; RCF; prediction; traction; braking; heavy haul; simulation; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Maintenance cost is one of the important issues in railway heavy haul operations. For the iron-ore company LKAB, these costs are mainly associated with the reprofiling and changing of the wheels of the locomotives and wagons. The main reason for the wheel damages is usually surface initiated rolling contact fatigue (RCF) on the wheels. READ MORE

  7. 10. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

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

    Abstract : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. READ MORE
