The Geochemistry, Distribution And Mobility Of Metals About An Abandoned Cu-Pb-Zn Mine At Mount Bulga, Orange, Nsw: Implications For Acid Rock Drainage, Daniel Knight
Science, Medicine & Health - Honours Theses
Mining activities at the abandoned Mount Bulga Cu-Pb-Zn-Ag deposit resulted in large amounts of previously buried sulfides being brought to the surface causing the potential of acid mine drainage to be a problem or concern. The pH values measured in the surface soils range from strongly acidic to neutral (3.6-7.9) but averaging mildly acidic (5.2). The distribution of metals in the soils show a distinct zonation between the different geological units clearly defining fault contacts between these units. The XRF analysis using the portable XRF was compared to a laboratory XRF instrument and most metals correlated well except for vanadium, …
