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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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.

  4. 4. Mineralogical and Geochemical Study of Acid Mine Drainage from 100 Years of Coal Mining in Svalbard (78° N)

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Andreas Rehn; [2020]
    Keywords : Acid rock drainage; Acid mine drainage; coal mine waste; Pyrite; Arctic; Svalbard; Spitzbergen;

    Abstract : Waste rock piles from coal mining of tertiary bituminous coal in Longyearbyen, Svalbard, show sulfide oxidation and subsequent acid mine drainage (AMD) production. The aim was to establish deeper understanding of AMD prediction based on Mineralogy and Geochemistry of coal and AMD samples. READ MORE
