  2. 1. Bacteria-sulfide mineral interactions with reference to flotation and flocculation

    Author : Annamaria Vilinska; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulfide and oxide ores have been developed during the years and these processes have been adopted by certain industries. READ MORE

  5. 3. Surface studies relevant to microbial adhesion and bioflotation of sulphide minerals

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

    Abstract : Biomineral beneficiation concerns the way in which microorganisms bring about the enrichment of an ore matrix. It involves the selective removal of undesired mineral constituents from an ore through microbe-mineral interactions in the processes such as selective flotation and flocculation. READ MORE

  7. 5. Leaching behaviour of rock materials and a comparison with slag used in road construction

    Author : Mia Tossavainen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Leaching characteristics are used for the evaluation of secondary materials used in road construction. In order to form a basis for comparison of the leachability, Swedish rock material have been investigated using the availability test NT ENVIR 003. READ MORE
