2. 1. Dynamics of aluminum use in the global passenger car system: Challenges and solutions of recycling and material substitution

   Author : Roja Modaresi; Norges teknisk-naturvitenskapelige universitet (NTNU); []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis analyzes the relationship between the design of vehicles, end-of-life vehicle (ELV) management, and global material production using aluminum as an example. Vehicle manufacturing, material industries and ELV management face different challenges. READ MORE

4. 2. On the surface quality of continuously cast steels and phosphor bronzes

   Author : Saud Saleem; Hasse Fredriksson; Michael Vynnycky; Toshihiko Emi Takaido Higashi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Continuous Casting; Steels; Ni-based alloy; Peritectic; Phosphor Bronzes; Simulation and Modeling; Teknisk materialvetenskap; Materials Science and Engineering; Industriell ekonomi och organisation; Industrial Engineering and Management; Metallurgical process science; Metallurgisk processvetenskap;

   Abstract : This thesis work concerns about the importance of the cast surfaces, surface phenomenon such as the formation of the oscillation marks and exudation and related defects including cracks and segregation that happened during the continuous casting. All of the investigated materials were collected during the plant trials while an in-depth analysis on these materials was performed at the laboratory scale with certain explanations supported by the schematic and theoretical models.

5. 3. 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.

6. 4. Geometallurgical programs – critical evaluation of applied methods and techniques

   Author : Viktor Lishchuk; Simon Michaux; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Abstract : Geometallurgy is a team-based multidisciplinary approach aimed at integrating geological, mineralogical and metallurgical information and yielding a spatial quantitative predictive model for production management. Production management includes forecast, control and optimization of the product quality (concentrates and tailings) and metallurgical performance (e. READ MORE

7. 5. Source, mobility and fate of critical Be, Bi, F and W from historical sulfidic-oxidic skarn tailings : Re-mining as remediation method?

   Author : Lina Hällström; Lena Alakangas; Olof Martinsson; Heather Jamieson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

   Abstract : There is a potential risk that geochemical cycles of several critical metals will be affected in the pristine environment, when mining of these metals increases to meet the demand in green technology. The identification of critical metals is based on the economic importance and vulnerability to supply restrictions. READ MORE
