1. Triaxialförsök och utvärdering av parametrar för modellering : Anrikningssand med sprött beteende
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/GeoteknologiSammanfattning : Efter det dammbrott som skedde vid Brumadinho i Brasilien under januari 2019, där hundratals människor miste sina liv, har frågor kring statisk liquefaction hos anrikningssand fått stort fokus inom gruvdammsindustrin. Statisk liquefaction kan modelleras med den konstitutiva modellen NorSand, där NorSand-parametrarna kan utvärderas från triaxialförsök. LÄS MER
2. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
3. Effect of increased vertical stress on the state of grains in tailings
Master-uppsats, Luleå tekniska universitet/GeoteknologiSammanfattning : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. LÄS MER
4. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : 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. LÄS MER
5. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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.
