  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. 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.

  4. 3. Mineralogical characterization of gold in the Aurora ore zone in the Björkdal gold mine, northern Sweden – implications for metal recovery

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

    Author : Krister Åström; [2022]
    Keywords : geology; Björkdal gold deposit; Skellefte district; gold; Au; Aurora ore zone; metal recovery; cold mounting; SEM; QEMSCAN; mineral association; grain size;

    Abstract : The Aurora zone is an ore zone which was recently discovered in the Björkdal gold mine, northern Sweden, and it has been the main focus of mining and exploration activities for the past few years (Pressacco et al., 2020). The purpose of this project is to determine how gold occurs in the Aurora zone. READ MORE

  5. 4. Reflection Seismic Survey for Characterising Historical Tailings and Deep Targeting at the Blötberget Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : EMMANUEL ALOFE; [2021]
    Keywords : reflection seismic; exploration; tailings; sustainability; circularity; tomography; reflektion seismisk; prospektering; gruvavfall; hållbarhet; cirkularitet; tomografi;

    Abstract : Iron has been an essential element to human development and iron-oxide deposits are known to host minerals that are labelled as critical raw materials (CRMs), especially in the EU. Therefore, ensuring a sustainable supply of CRMs require access to both primary and secondary sources of their host deposits such as iron oxides. READ MORE

  6. 5. Determination of dry density in tailings with a Dynamic Cone Penetrometer :

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

    Author : Patrik Hagström; [2017]
    Keywords : dynamic cone penetrometer; tailings dam; tailings beach; tailings;

    Abstract : Today mines produce metals which are used for everyday products by people worldwide. When metals are produced, waste products known as tailings are generated. These tailings are commonly stored in impoundments, surrounded by embankment dams. The demands from the society are constantly increasing regarding the quality and safety of dams. READ MORE
