Environmental Considerations of Uranium Mining and Milling

There have been many changes in environmental control techniques since the early days of uranium mining and milling, when liquid mill effluents and often mill tailings were discharged directly into nearby streams. With today's stringent environmental controls, the uranium miner must be as aware of regulatory requirements as he is of techniques in mining, milling, and in-situ recovery. The time delays involved in bringing a uranium project on line dictate that the proposed facility be designed with a view not only of present regulations, but also of those which may be in effect when the facility is completed. While such predictions are difficult, it's almost certain that regulatory agencies will exercise even more environmental control over future uranium mining and milling operations, using the past errors of the 1950's as justification for increasingly stringent controls.
