Solution (in situ leach) mining of uranium: an overview

In-situ solution mining and processing have many advantages over conventional uranium mining-and-milling methods. There is, however, a significant potential for ground-water contamination, but it can be minimized by successful restoration of the mined aquifer, limiting leachate excursions, and control of leakage from waste storage ponds.
