Thesis Topic |
Long
term evolution of gold tailings geochemistry and the buffering capacity of
added lime: Kidston Gold Mine. |
|
Supervisors |
Dr Thomas Baumgartl
Dr Mansour Edraki |
|
Project outline |
Seeping waters from tailings dams contain high levels of environmentally
dangerous elements such as Sulphate and Arsenic. The release of these
elements into natural systems is controlled by the internal chemical and
physical processes within tailings dams. In order to buffer the
acid-generating potential of tailings, lime is added during processing.
This project is investigating the long term changes in the tailings
chemistry and will model what happens to seeping water when the lime
buffering acidity is consumed.
