  2. 1. Particle generation for geometallurgical process modeling

    Author : Pierre-Henri Koch; Jan Rosenkranz; Luleå tekniska universitet; []
    Keywords : 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

  4. 2. Computational methods and strategies for geometallurgy

    Author : Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

    Author : Mehdi Parian; Pertti Lamberg; Jan Rosenkranz; Julie Hunt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; breakage characterization; ore texture; iron ore; modal mineralogy;

    Abstract : 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.

  6. 4. Selective Comminution Applied to Mineral Processing of Critical Metals

    Author : Lorena Guldris Leon; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective comminution; compressive crushing; analytical method; minerals; critical metals; elements.;

    Abstract : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. Due to the vital economic importance and limited supply, growing interest places these metals on the critical metals risk list. READ MORE

  7. 5. Analysis and Modelling of Mineral and Element Composition in Compression Breakage
