  1. 1. Utilizing wood ash to stimulate algal growth in mine waters from northern Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Katelyn Murphy; [2023]
    Keywords : acid rock drainage; acid mine drainage; controlled eutrophication;

    Abstract : Acid rock drainage (ARD), caused by the oxidation of sulphide bearing minerals, continues to be an environmental impact of both closed and operational mines, leading to waters with low pH values and high metal concentrations (Park et al., 2019). READ MORE

  3. 2. 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

    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

  6. 5. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    University essay from Linköpings universitet/Tema Miljöförändring
