    Author : Simon Fogelqvist; [2008]
    Keywords : gruvor; gruvverksamhet; återställa; återvinna; efterbehandla; landskap; gestaltning;

    Abstract : Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. READ MORE

  4. 13. In-situ Removal of Hydrogen Sulphide from Landfill Gas : Arising from the Interaction between Municipal Solid Waste and Sulphide Mine Environments within Bioreactor Conditions
