    In Situ Leach and Conventional UraniumRecovery Methods

    Jun 20, 2018 · From 1972 through 1985, uranium recovery in Texas was dominated by conventional mining and milling. More recently, companies (licensees) have been using In Situ Leaching (ISL), a process that makes possible the recovery of uranium without disturbing the natural surface, generating dust, or producing waste known as tailings.

    Radioactive Waste From Uranium Mining and Milling

    After uranium is extracted from rock, the processes leave behind radioactive waste. Uranium eventually decays to radium, and then radon. Open pit uranium milling and in situ mining sites do not pose a radon risk to the public or miners.

    For uranium ores, the leachate might be acid or sodium bicarbonate. Soluble salts. In-situ leach is broadly used to extract deposits of water-soluble salts like sylvite (potash), halite (rock salt, sodium chloride), and sodium sulfate. It has been used in the US state of Colorado to take out nahcolite (sodium bicarbonate).

    Uranium Mining Processing and Reclamation Uranium

    In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the uranium ore in the ground, and recovering the uranium by dissolving it from the uranium-bearing minerals by injecting carbonated solution or mild acid and pumping the leached uranium in a pregnant solution to the surface where the metal can be recovered (Figure 4.10). Consequently, there …
