  • Groundwater restoration following in-situ recovery (ISR

    Increased interest in nuclear energy has led to proposals for renewed development using both underground mining and uranium in situ recovery (ISR). When feasible, ISR greatly reduces waste generated by the mining and milling processes, however, the ability to restore ground water to acceptable quality after ISR ends is uncertain. This research investigated two methods of stabilizing

    Abstract. The use of the ’in situ leach’ technique of uranium mining is a new development in Australia’s expanding uranium industry. To date there have been three sites of pilot leach mines at Beverley (1998) and Honeymoon (1982, 1998-2000) in South Australia and at Manyingee (1985) in Western Australia.
