11. Geochemical effects of soil cover remediation on sulphide-rich tailings at the Kristineberg mine, northern Sweden
Sammanfattning : Remediation of mine waste by the application of till cover is one of the more common methods used in Sweden to prevent oxidation of sulphide-rich minerals. Although the general conclusion from Swedish state-of-the-art field studies is that dry covers may be effective, they are expensive to construct. LÄS MER
12. Sulphide-rich tailings remediated by soil cover : evaluation of cover efficiency and tailings geochemistry, Kristineberg, northern Sweden
Sammanfattning : The efficiency of soil cover as a method of remediation of sulphide-rich tailings has been studied at an impoundment at the Kristineberg mine, Northern Sweden. Two variations of soil cover were used in the remediation. The major part of the impoundment was covered with a 1.0 m layer of till where the groundwater table was shallow. LÄS MER

14. Nitrogen and phosphorus interactions and transformations in cold-climate mine water recipients
Sammanfattning : Process water discharged from mine sites may contain elevated concentrations of nitrogen (N) and phosphorus (P), which both are nutrients for phytoplankton and macrophytes. Thus, discharge of nutrient rich mine water can result in algal blooms, eutrophication, oxygen deficiency and changed species composition in the recipients. LÄS MER
15. Nitrogen effluents from mine sites in northern Sweden : nitrogen transformations and limiting nutrient in receiving waters
Sammanfattning : Process water discharged from mine sites may contain elevated concentrations of nitrogen (N) and phosphorus (P), which both are nutrients for algae and aquatic plants. Thus, discharge of nutrient rich mine water can result in algal blooms, eutrophication, oxygen deficiency and changed species composition in the receiving waters. LÄS MER
