Progress Report on the Wismut Decommissioning Project at the Flooded Königstein Uranium Mine
Prospecting for uranium began in the Upper Cretaceous sandstones of the Elbe river valley southeast of Dresden in 1961. Systematic mine operations commenced 1964. As a response to low and decreasing ore grades alternatives to conventional mining were precociously searched for. Development of in-situ leaching technology started at the end…

Innovative Monitoring Measures in the Phase of Post-Mining
Mining activities often influence huge areas which can only be observed efficiently with remote sensing methods. Recently the European Programme of Earth Observation Copernicus began to offer the opportunity to pursue this monitoring with innovative attempts in the production phase as well as in the post-mining phase. The combination of…
