  1. 1. Development of the mineralogical path for geometallurgical modeling of iron ores

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Mehdi Parian; Luleå tekniska universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The demands for more effective utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross discipline called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

  2. 2. Sulphide Minerals: Surface Oxidation and Selectivity in Complex Sulphide Ore Flotation

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Alireza Javadi; Luleå tekniska universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Metal and energy extractive industries play a strategic role in the economic development of Sweden. At the same time these industries present a major threat to the environment due to multidimensional environmental pollution produced in the course of ageing of ore processing tailings and waste rocks.

  3. 3. Geometallurgical programs – critical evaluation of applied methods and techniques

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Viktor Lishchuk; Luleå tekniska universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Mineralteknik;

    Sammanfattning : Geometallurgy is a team-based multidisciplinary approach aimed at integrating geological, mineralogical and metallurgical information and yielding a spatial quantitative predictive model for production management. Production management includes forecast, control and optimization of the product quality (concentrates and tailings) and metallurgical performance (e. LÄS MER

  4. 4. Wet Low-Intensity Magnetic Separation: Measurement methods and Modelling

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jan Stener; Luleå tekniska universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. LÄS MER

  5. 5. Test Methods for Characterising Ore Comminution Behavior in Geometallurgy

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Abdul Mwanga; Luleå tekniska universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Mineralteknik;

    Sammanfattning : 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. LÄS MER
