Uranium Mining, Processing, and Enrichment. Ian Hore-Lacy, in Encyclopedia of Energy, 2004. 1.3 In Situ Leach (ISL) Mining. In situ leaching (ISL), also known as solution mining, involves leaving the ore where it is in the ground and using liquids that are pumped through it to recover the minerals out of the ore by leaching. Consequently there is little …

The leaching mining has many advantages over traditional mining methods in the following ways: (1) Low energy consumption. (2) Safe operations and good working conditions. (3) Low costs, low infrastructure costs, fast mine construction, and high degree of automation. (4) Environmental friendliness. (5) High resource recovery rate.
In-situ leaching (ISL) methods, however, are increasingly allowing certain deposits to be mined without excavation, sidestepping some of the most destructive, and costliest, parts of mining. What is …

Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

A generalized diagram of how ISL is carried out. As the name implies, in-situ leaching involves the leaching and extraction of metals from underground ore bodies. The process is similar to heap leaching, where ore is extracted and piled up so leaching solutions can be circulated through it, except that ISL involves no excavation. In general ...
Bacterial activity can be utilised to catalyse the oxidation of iron in sulfides (ferro to ferric state). In this process, sulphuric acid and exothermic heat is generated which improves the acid balance in the heap and raise the heap temperature, respectively.
