1. 21. 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.

3. 22. High ash non-coking coal preparation by tribo-electrostatic dry process

   Författare :Ranjan Dwari; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : Coal is the single largest fossil fuel used world-wide and accounts for more than 60% of the total commercial energy consumed. Between 60 to 80% of this coal is used for electric power generation and most of which through a system of pulverised coal combustion. LÄS MER

4. 23. X-ray microcomputed tomography (µCT) as a potential tool in particle-based geometallurgy

   Författare :Pratama Istiadi Guntoro; Yousef Ghorbani; Jan Rosenkranz; Veerle Cnudde; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray microcomputed tomography; Mineralogy; Texture; Liberation; Geometallurgy; Mineral Processing; Mineralteknik;

   Sammanfattning : In recent years, automated mineralogy has become an essential tool in geometallurgy. Automated mineralogical tools allows the acquisition of mineralogical, textural, and liberation information of ore samples. Such information is essential in the context of geometallurgy where it is needed for estimating the process response of the ores. LÄS MER

5. 24. Microbial adhesion and surface modifications of sulphide minerals relevant to flotation and flocculation

   Författare :Annamaria Vilinska; Ponisseril Somasundaran; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulphide and oxide ores have been developed during the years and these processes have been adopted by certain mineral industries. LÄS MER

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

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

   Sammanfattning : 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.
