Following an introduction to the conceptual site model approach, examples of the application of this
methodology to different mine closure problems are illustrated. Generally, under the large-scale WISMUT
remediation project in Germany, the conceptual site model approach proved to be very powerful in assisting
with decision analyses regarding the optimization of remedial measures. This is due to the fact that the water
and contaminant load balance of the different mining objects (tailings facilities, piles, open pits,
underground mines and processing plants) in particular, can be very effectively represented by flexible
multi-compartment models. The software platform GoldSimTM is an ideal tool for the required iterative
approach. Additionally, applications of the conceptual site model approach described in this paper illustrate
that meaningful results can be achieved with a multi-compartment approximation using limited data, even
for a complex remedial problem.
