    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  3. 2. Evaluation of tomographic methods for limestone characterization : Using synchrotron-based X-ray tomography to determine porosity, internal structure and internal distributions in limestone

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Albert Askengren; [2021]
    Nyckelord :Limestone; X-ray tomography; Synchrotron; XRT; Synchrotron-based XRT;

    Sammanfattning : Limestone is a raw material in the cement and quicklime industry and knowledge about limestone characteristics can help improve and optimize production processes. In the end this can lead to a reduction in CO2 emissions from the industry. In this project X-ray tomography (XRT) was used to examine limestone samples. LÄS MER

  4. 3. 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)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER
