  3. 2. Application of Chemical Additives in Minerals Beneficiation – Implications on Grinding and Flotation Performance

    Författare :Vitalis Chipakwe; Saeed Chehreh Chelgani; Jan Rosenkranz; Tommy Karlkvist; Irina Chernyshova; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Grinding aid; Flowability; Dry grinding; FT4 Powder Rheometer; Surface properties; Rheology; Flotation; Polymers; Surface chemistry; Green Chemistry; Mineral Processing; Mineral Processing; Mineralteknik;

    Sammanfattning : The application of chemical additives, known as grinding aids (GAs), dates to 1930 in the cement industry. Unlike the cement industry, where the use of GAs is in the final processing step, it could be one of the first processing steps in ore beneficiation. LÄS MER

  4. 3. Computational methods and strategies for geometallurgy

    Författare :Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; Luleå tekniska universitet; []
    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

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

    Författare :Mehdi Parian; Pertti Lamberg; Jan Rosenkranz; Julie Hunt; Luleå tekniska universitet; []
    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.

  7. 5. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture

    Författare :Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Loading mechanism; Ore texture; Breakage mode; Fracture energy; Fragmentation; Breakage mechanism; Statistical analysis; 3D Deformation; Crack quantification; Mineral Processing; Mineralteknik;

    Sammanfattning : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. LÄS MER
