  1. 21. Optimization Framework for Crushing Plants

    Författare :Kanishk Bhadani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minerals Processing; Industry 4.0; Multi-Objective Optimization MOO ; Screening; Process Optimization; Process Improvement; Modelling; Comminution; Key Performance Indicators KPIs ; Classification; Multi-Disciplinary Optimization MDO ; Crushing; Dynamic Simulations;

    Sammanfattning : Optimization is a decision-making process to utilize available resources efficiently. The use of optimization methods provide opportunities for continuous improvements, increasing competitiveness, trade-off analysis and as a support tool for the decision-making process in industrial applications.

  3. 22. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case

    Författare :Jane Mwaba Mulenshi; Jan Rosenkranz; Saeed Chehreh Chelgani; Urs Peuker; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining waste; Historical tailings; Conceptual framework; Critical raw materials; Tungsten; Scheelite; Characterization; Mineral liberation analysis; Beneficiation; Reprocessing; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

    Sammanfattning : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.

  4. 23. On Subscale Flight Testing : Applications in Aircraft Conceptual Design

    Författare :Alejandro Sobron; Petter Krus; David Lundström; Zdobyslaw Goraj; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.
