  2. 11. DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls

    Author : Johannes Quist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Modelling; HPGR; Comminution; DEM; Simulation; Crushing; Minerals Processing; Cone Crusher;

    Abstract : The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills.

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

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

    Abstract : 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. READ MORE

  5. 13. High intensity and high gradient magnetic separation in mineral processing

    Author : Jan A. Jirestig; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Natural minerals often lack well defined magnetic susceptibilities. Instead they must be thought of as occurring in a susceptibility range where the bulk susceptibility is affected by present impurities. Inclusions or foreign atoms in solid solution may alter a materials magnetic properties to a large extent. READ MORE

    Author : Gang Chen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : .... READ MORE

  7. 15. On the use of immersive technologies in the professional education of mineral processing

    Author : Pedro A. de S. Bergamo; Yousef Ghorbani; Jan Rosenkranz; Emilia Sofia Streng; Saija Luukkanen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Training Evaluation; Modelling and Simulation; Gamification; User Experience; Mineral Processing; Mineralteknik;

    Abstract : With the advance of technology, many educators started implementing immersive technologies like simulators and gamified learning applications to improve the trainings of process operators. However, it is noted that the minerals sector is significantly behind other industries, for instance, the chemical industry, especially when it comes to the evaluation of these types of trainings.
