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

    Author : Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  2. 2. Effects of loading mechanisms and texture on ore breakage – A multidimensional study

    Author : Parisa Semsari Parapari; Magnus Evertsson; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Breakage mechanism; Loading mechanism; Ore texture; Liberation; Comminution; Mineral Processing; Mineralteknik;

    Abstract :  In comminution machines, the product properties (particle size distribution, mineral liberation characteristics) and process consumables (energy for size reduction, wear) are affected by various parameters. On the one hand, understanding and optimizing these parameters can provide an energy efficient process and a specified product. READ MORE

  3. 3. Quality-Driven Production of Aggregates in Crushing Plants

    Author : Magnus Bengtsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breakage; crushing; simulation; modelling; Keywords: aggregate quality; particle shape;

    Abstract : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. 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. Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing

    Author : Haijie Li; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Dynamic modeling; AG SAG mill; Fundamental modeling method; Data-driven modeling method; Pebble crushing; Cone crusher; Comminution process;

    Abstract : Grinding is one of the most energy-consuming processes in the mining industry. As a critical part of the comminution process, autogenous grinding (AG) or semi-autogenous grinding (SAG) mills are often used for primary grinding. READ MORE
