3 Technologies in Exploration, Mining, and Processing ...
Insitu mining is the "removal of the valuable components of a mineral deposit without physical extraction of the rock" (Bates and Jackson, 1987). Insitu leaching is a type of insitu mining in which metals or minerals are leached from rocks by aqueous solutions, a hydrometallurgical process (American Geological Institute, 1997).

Bioleaching |authorSTREAM
In situ leach mining involves drilling boreholes down into an ore body, pumping a leaching fluid into the ore and then pumping the resulting solution to the surface to extract the uranium. The leaching fluid is sometimes a combination of acids or sometimes alkaline solution. The type of the solution used depends on the type of the ore body.
