1. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experiments
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Oxidation of sulfidic mine waste is of significant environmental concern due to the consequent formation of acid rock drainage (ARD), deteriorating the water quality of natural water systems. Iron (Fe) and sulfur (S) are two major redox elements involved in these reactions and typically the major redox-sensitive elements (whose solubility, speciation, and mobility are affected by pH and Eh) in water affected by ARD.

2. OIL SHALE ASH UTILIZATION IN INDUSTRIAL PROCESSES AS AN ALTERNATIVE RAW MATERIAL
Master-uppsats, KTH/Industriell ekologiSammanfattning : Oil shale is a fine-grained sedimentary rock with the potential to yield significant amounts of oil and combustible gas when retorted. Oil shale deposits have been found on almost every continent, but only Estonia, who has the 8th largest oil shale deposit in the world has continuously utilized oil shale in large scale operations.

3. Mapping leachates and subsurface structures using different geophysical methods.
Master-uppsats, KTH/Mark- och vattenteknikSammanfattning : The enrichment of ore produces large amounts of sulfur and metal-rich residual waste called tailings, which need to be deposited and stored for a long time. When the tailing is oxidized, large amounts of protons and metals are dissolved and diffuse to the groundwater. LÄS MER
4. Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues
Kandidat-uppsats, Institutionen för geovetenskaperSammanfattning : Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residues Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. LÄS MER
