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

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

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

    Abstract : 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. Uranium Mineralizations at Kiirunavaara,Northernmost Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Diego Segovia Menard; [2022]
    Keywords : kiirunavaara; uranium; EPMA; water; hydrothermal;

    Abstract : In recent years, a variably high amount of uranium (U) and radon (Rn) were found in the water and airof the Kiirunavaara mine in Kiruna, northern Sweden. The Swedish Agency for Marine and WaterManagement (Havs och vattenmyndigheten) has maximum limits for “special polluting substances” inwater that is released to natural recipients (HVMFS 2019:25), therefore, the mining company LKAB,owner and operator of the Kiirunavaara mine, decided to conduct a study to investigate the issueregarding these findings, triggering this master thesis.

  5. 4. Characterization of the cobalt content in zinc ore from Zinkgruvan, Sweden

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

    Author : Ingeborg Hjorth; [2022]
    Keywords : Zinkgruvan; Bergslagen; Cobalt; Sphalerite; Pyrrhotite; Safflorite;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. READ MORE

  6. 5. Geochemical and Mineralogical Comparison of XRT-XRF Scanning Technology Versus Traditional Analysis of Drill Core from the Assarel Porphyry Copper-Gold Deposit (Panagyurishte District, Bulgaria)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Diego Delgado Yanez; [2020]
    Keywords : Assarel porphyry copper; GeoCore X10; Sustainable mining; XRT XRF; mineral characterization; geochemical characterization; X-MINE Project;

    Abstract : Ongoing, environmental and economic matters related to mining sustainability and its impacts are leading to the search for new ways to asses and extract commodities more efficiently. A key aspect in the shift to more sustainable mining is the rapid, digital characterization of orebody mineralogy and geochemistry to help optimize the extractive process. READ MORE
