In-Situ Leaching Studies of Uranium Ores: Phase V

摘要

In situ uranium leaching involves passing a lixiviant and oxidant solution through the uraniferous ore body. As the solution progresses through the ore body, the uranium is oxidized to a soluble state and taken into solution. The uranium-laden solution is removed from the ore body and the uranium is recovered in a plant on the surface. In this study, a laboratory technique for simulating the underground leaching process was developed and used to determine the effects of leaching variables on the permeability, uranium recovery, and ore aquifer environment. Agitation and column leach tests were conducted using ore samples from Wyoming and Texas. The information obtained from these tests provides a better understanding of the leaching process.
