5. 19. Preventing Acid Rock Drainage Formation from Sulfidic Waste Rock Using Secondary Raw Materials

   Författare :Elsa Nyström; Lena Alakangas; Andrzej Cwirzen; Christian Maurice; Jose Miguel Nieto; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

   Sammanfattning : One of the central and most challenging environmental problems related to mining is acid rock drainage (ARD) formation. The drainage is characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. LÄS MER

7. 20. Engineering information integration and application development using object-oriented mediator databases

   Författare :Mattias Nyström; Luleå tekniska universitet; []
