Kinetic development of oxidation zones in tailings dams with specific reference to the Witwatersrand gold mine tailings dams
Expanded Title:The understanding of oxidation zones and phreatic water surfaces plays a very important role in the prediction of acid rock drainage (ARD). Frequently, assumptions on the development of oxidation zones and phreatic surfaces are made based on rule-of-thumb experience and extrapolations from other sites / experiences. The uncertainty regarding the depth and progression of the oxidation zonesn is one of the major drawbacks in geochemical assessment and predictive modelling and the establishment of accurate oxidation profiles and determination of phreatic surface becomes an important issue for ARD prediction.
