  1. 1. Gamification for technology-enhanced mineral value chain teaching and learning: serious gaming for geometallurgy concept

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Lilian Schleret; [2024]
    Nyckelord :Gamification; Malmberget; Geometallurgy; Synthetic model;

    Sammanfattning : The concept of gamification is being increasingly explored and applied to offer new teaching or training tools to teachers, students or employees. The field of geology and geometallurgy wasn’t particularly discussed in the topic of gamification. LÄS MER

  3. 2. Investigating the potential of systematic optical petrography in a geometallurgical context : A case study on boulder characterization from Rajapalot property, Finland

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Annie Björk; [2023]
    Nyckelord :Petrography; optical microscopy; scanning electron microscopy; geometallurgy; mining value chain; Peräpohja belt;

    Sammanfattning : Geometallurgy describes a holistic approach to mining (integrating geological, metallurgical, geotechnical, environmental, and more parameters) with the goal to improve the efficiency and sustainability of a mining operation. The potential of systematic optical petrography in a geometallurgical context was investigated in this study, as well as how petrography may be useful across disciplines in several blocks of the mining value chain.

  4. 3. A process mineralogy study of grinding characteristics for the polymetallic orebody, Lappberget Garpenberg

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Gustav Lood Stark; [2021]
    Nyckelord :Automated mineralogy; autogenous milling; grinding characteristics; mineral characterization; process mineralogy geometallurgy; blending strategies; energy consumption; throughput; scanning electron microscope SEM ;

    Sammanfattning : Most of the high-grade ores have been depleted globally, thus the effective processing of the low-grade and complex ores require a comprehensive mineral characterization through the process mineralogy/ geometallurgical approaches. 30-70 % of the total energy consumption in mining comes from the comminution step in mineral processing.

  5. 4. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Raoul Schmitt; [2021]
    Nyckelord :Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

    Sammanfattning : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

  7. 5. Textural characterization of gold in the Björkdal gold deposit, northern Sweden.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Fredrik Westberg; [2021]
    Nyckelord :Björkdal gold deposit; gold; gold-telluride; SEM; mineral association; grain size; geometallurgy;

    Sammanfattning : The Björkdal gold deposit is located in the eastern part of the Skellefte district, northern Sweden. Twenty thin sections from four production areas in the open pit and four drifts from the underground mine were analysed for mineral association and grain size distribution of gold. LÄS MER
