In-Situ Leach Uranium Mining: A Review

Energy Exploration & Exploitation, 1983
This paper describes a current technique (ISL) in uranium mining, i.e. by solution or ‘leaching’. Although it is not yet widespread, it promises a relatively cheap and efficent means of extracting uranium from orebodies in sandstone deposits, such as those of the USA, Australia and Japan.
