Uranium in Situ Mining Research by the United States Bureau of Mines- -a Review.
Paper in in Situ Leaching of Uranium: Tech Env & Econ Aspects Vienna 1989 :37-62
The Bureau of Mines initiated its in situ mining research program in 1974 to advance in situ mining as a viable alternative to conventional open pit and underground mining methods. At first, research work was conducted in two principal areas--fluid flow modeling and geochemical modeling to represent leaching reactions in the ore body. Subsequently, the work effort evolved into a multiphase in situ mining research program designed to find a more economical way of mining while minimizing negative impacts on the environment. This paper discusses aspects of the Bureau's laboratory and field research accomplishments on the following topics: (1) permeability of uranium-bearing sandstone, (2) environment and restoration of ground water, (3) fluid flow and geochemical modeling, (4) environmentally attractive leach solutions, (5) well construction and completion, and (6) cost and sensitivity analysis for uranium in situ mining.
