    Nyckelord :Sulphate; iron ore mine; process water; anhydrite; laboratory grinding; equilibrium calculations; mass balance;

    Sammanfattning : Sulphate-rich wastewater is an increasing concern for industries as LKAB. The water chemistry of the LKAB Kiruna water system is characterized by high alkalinity, high pH (pH 7.5-9.0) and high concentrations of chemical species and soluble minerals. LÄS MER

  4. 3. On the mechanism of H2O2 decomposition on UO2-surfaces

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Darius Pakarinen; [2018]
    Nyckelord :hydrogen peroxide decomposition; uranium dissolution; coumarin scavenging;

    Sammanfattning : Deep geological repository has been investigated as a solution for long term storage of spent nuclear fuel in Sweden for more than 40 years now. The Swedish nuclear fuel and waste management company (SKB) are commissioning the deep repository and they must ensure that nuclear waste is isolated from the environment for thousands of years.

  5. 4. Water Courses in Kvarntorp : An Evaluation of Water Chemistry from Monitoring Data 1994-2012

    Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Lovisa Karlsson; [2014]
    Nyckelord :Kvarntorp; water chemistry; shale; heavy metals; contaminants; refuse dump; uranium; seasonal change; Kumla;

    Sammanfattning : The Kvarntorp area, some 200 km SW of Stockholm, Sweden, is a former mining site for alum shale. Kvarntorpshögen is a refuse dump from the hydrocarbon extraction during 1940-1965. The area is also dotted by abandoned quarries, which most are water filled today. The area is divided into two watersheds; the central and the eastern. LÄS MER

  7. 5. Effects of uranium mining on groundwater - Geochemical modeling of aqueous uranium speciation due to changing redox conditions.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Adrian Gronowski; [2013]
    Nyckelord :Uranium mining; Uranium speciation; Uraninite; Uranium groundwater transport; Visual Minteq;

    Sammanfattning : As a consequence of rising uranium prices an interest in Sweden’s U deposits has emerged. This raises the important question of the possible environmental impacts of U mining operations. One of the most significant and serious issues is the contamination of groundwater by U following mining activities. LÄS MER
