In situ leach Wikipedia

First used in Wyoming in the 1950s, insitu leaching (ISL) mining accounts for most uranium production in the United States. In situ leaching – what it is ISL involves injecting chemicals, called “lixivants” into an aquifer that contains a uranium ore body ( deposit). The chemicals used are typically sulfuric acid or ammonium carbonate.

Acid Leaching of Uranium

It is preferred over carbonate leaching because of its greater efficiency in recovering uranium. Consequently much research has been done on the factors which influence the kinetics of the oxidation of uranium, as well as those which influence the leaching process as a whole. This knowledge can be applied to the study of in situ leaching.
