   Sammanfattning : This thesis is a study of Holocene sapropels from two semi-enclosed seas; the Baltic Sea and the Mediterranean Sea. Sapropels are sedimentary layers with organic C > 2%. LÄS MER

4. 3. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

   Författare :Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; Earth sciences; Geovetenskap;

   Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER
