  1. 6. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Shenelle Agard; [2023]
    Keywords : tailings storage facility; critical raw materials; machine learning; mine valorisation;

    Abstract : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. READ MORE

  3. 7. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : CELESTINE IFEANYI UGWUOKE; [2023]
    Keywords : Tailings; Sequential extraction; Mineralogy; Sulphate;

    Abstract : This research project investigated the high concentration of sulphate in a tailing pond at LKAB and the characteristics and behavior of sulphate minerals in different areas of the pond. The sampling of the tailings was carried out at Nine stationary sampling points. READ MORE

  4. 8. Biochar from separated digestate and pig manure as soil amendment

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

  5. 9. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nsioh Elvis Nkioh; [2022]
    Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Abstract : 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. READ MORE

  6. 10. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

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

    Author : Adrian Larsson; [2022]
    Keywords : Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

    Abstract : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. READ MORE
