1. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : This research project investigated the high concentration of sulphate in a tailing pond at LKAB and the characteristics and behavior of sulphate minerals in different areas of the pond. The sampling of the tailings was carried out at Nine stationary sampling points. LÄS MER
2. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.
