  1. 6. Physico-chemical characterisation of microbial cell surface and bioflotation of sulfide minerals

    Författare :Prashant K. Sharma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Biomineral beneficiation concerns the way in which microorganisms bring about the enrichment of an ore matrix. It involves the selective removal of undesirable mineral constituents from an ore through microbe-mineral interactions in the process such as selective flotation and flocculation. LÄS MER

  4. 8. The technology of processing antimony-bearing ores

    Författare :Thomas Lager; []
    Nyckelord :;

    Sammanfattning : Several aspects of the process technology for treatment of antimony-bearing ores have been studied. The feasibility of separating contaminant antimony minerals as early as the mine planning stage is discussed. LÄS MER

  5. 9. Triboelectric charge characteristics and electrical separation of industrial minerals

    Författare :Hamid-Reza Manouchehri; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Despite the fact that triboelectric separation process has not been completely perceived, it pronounced to be environmentally amiable and economically viable for minerals and wastes beneficiation, especially when fine particles with relatively similar electrical properties are being to be separated. Since the method mainly depends on the charges developed on particles for a successful separation, it is necessary to develop different charge polarities on minerals undergoing separation. LÄS MER

  7. 10. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Författare :Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. LÄS MER
