  2. 2. Computational methods and strategies for geometallurgy

    Author : Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; minerals; machine learning; textures; decision-making; Mineral Processing; Mineralteknik;

    Abstract : 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. READ MORE

  3. 3. X-ray microcomputed tomography (µCT) as a potential tool in Geometallurgy

    Author : Pratama Istiadi Guntoro; Yousef Ghorbani; Jan Rosenkranz; Matthew Pankhurst; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; X-ray microcomputed tomography; geometallurgy; automated mineralogy; ore characterization; Mineral Processing; Mineralteknik;

    Abstract : In recent years, automated mineralogy has become an essential tool in geometallurgy. Automated mineralogical tools allow the acquisition of mineralogical and liberation data of ore particles in a sample. These particle data can then be used further for particle-based mineral processing simulation in the context of geometallurgy. READ MORE

  4. 4. Particle generation for geometallurgical process modeling

    Author : Pierre-Henri Koch; Jan Rosenkranz; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; ore texture; texture classification; breakage simulation; process modeling; Mineralteknik; Mineral Processing;

    Abstract : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. READ MORE

  5. 5. Sampling from large flotation cells : An invastigation of spatial distribution

    Author : Lisa Malm; Jan Rosenkranz; Tommy Karlkvist; Anders Sand; Nils-Johan Bolin; Pertti Lamberg; Luleå tekniska universitet; []
