1. Utilizing wood ash to stimulate algal growth in mine waters from northern Sweden
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : 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).

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. Metal mobility and transport from an oil-shale mine, Lake Nõmmejärv, Estonia
Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : Mining activities have a large impact on the environment, for example by the release of heavy metals from acid mine drainage and erosion of mine waste. North-eastern Estonia has the largest commercially exploited oil-shale deposit in the world. LÄS MER
4. Mineralogical and Geochemical Study of Acid Mine Drainage from 100 Years of Coal Mining in Svalbard (78° N)
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : 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. LÄS MER
5. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.
