  2. 21. Physico-chemical characterisation of microbial cell surface and bioflotation of sulfide 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 undesirable mineral constituents from an ore through microbe-mineral interactions in the process such as selective flotation and flocculation. READ MORE

  4. 22. Test Methods for Characterising Ore Comminution Behavior in Geometallurgy

    Author : Abdul Mwanga; Hakan Benzer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Comminution test methods used within mineral processing have mainly been developed for selecting the most appropriate comminution technology for a given ore, designing a grinding circuit as well as sizing the equipment needed. Existing test methods usually require comparatively large sample amounts and are time-consuming to conduct. READ MORE

  5. 23. Effects of loading mechanisms and texture on ore breakage – A multidimensional study

    Author : Parisa Semsari Parapari; Magnus Evertsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Breakage mechanism; Loading mechanism; Ore texture; Liberation; Comminution; Mineralteknik; Mineral Processing;

    Abstract :  In comminution machines, the product properties (particle size distribution, mineral liberation characteristics) and process consumables (energy for size reduction, wear) are affected by various parameters. On the one hand, understanding and optimizing these parameters can provide an energy efficient process and a specified product. READ MORE

  6. 24. Traceability in continuous grinding circuits

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

    Abstract : Traceability is the means to identify and follow real or imaginary lots through a process chain. It gives the opportunity to back-track a chain of events, or to predict process outcomes given the origin of a lot. Traceability can be used in different areas, e.g. READ MORE

  7. 25. Influence of variations in feed ore characteristics on autogenous grinding

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

    Abstract : In autogenous mills, the grinding media derives from the feed ore itself. Variations in feed ore properties will therefore affect the grinding charge and thus, the resulting ground product will vary. READ MORE
