  1. 1. Computational methods and strategies for geometallurgy

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; minerals; machine learning; textures; decision-making; Mineral Processing; Mineralteknik;

    Sammanfattning : At the interface of geology and mineral processing, geometallurgy is a powerful tool for enhancingresource efficiency. A spatial model that represents the ore body in terms ofmineralogyand physical properties is combined with a process model that describes the concentrationprocess. LÄS MER

    Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER

  3. 3. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling

    Detta är en avhandling från Luleå University of Technology

    Författare :Mehdi Parian; Pertti Lamberg; Jan Rosenkranz; Hunt Julie; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; breakage characterization; ore texture; iron ore; modal mineralogy;

    Sammanfattning : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject 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.

  4. 4. Development of a geometallurgical testing framework for ore grinding and liberation properties

    Detta är en avhandling från Luleå University of Technology

    Författare :Abdul-Rahaman Mwanga; Jan Rosenkranz; Hakan Benzer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grindability test; mineral texture; breakage properties; mineral liberation; process modeling; geometallurgy; Mineral Processing; Mineralteknik;

    Sammanfattning : Efficient measurement methods for comminution properties are an important prerequisite for testing the variability of an ore deposit within the geometallurgical context. This involves the investigation of effects of mineralogy and mineral texture on the breakage of mineral particles. 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; [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
