  1. 1. 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. 2. Effect of increased vertical stress on the state of grains in tailings

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Shane Aulestia; [2023]
    Keywords : Tailings; Tailings dams; Breakage; Oedometer; Image acquisition analysis; Avfall; Avfallsdammar; Brytning; Ödometer; Bildinsamling och analys;

    Abstract : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. READ MORE

  4. 3. 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

  5. 4. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : John Winlund; [2022]
    Keywords : backfilled tailings; Dannemora mine; iron ore; rock stability; stopes; återfylld anrikningssand; Dannemoragruvan; järnmalm; bergstabilitet; öppna brytningsrum;

    Abstract : The cut-off grade determines what rock mass are economic to mine. At the Dannemora mine, in eastern Bergslagen, Sweden, previously processed ore generated tailings (enrichment sand) with an iron content of 21-22 % that was backfilled into large open bodies (stopes) in the mine between 2013-2015.

  6. 5. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Emma Flodin; [2022]
    Keywords : Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

    Abstract : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. READ MORE
