Environmental hydrogeology of in situ leach uranium …

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.
