Solution Mining

Most solution mining is by heap leaching, in which the extractant solution is trickled over broken ore on the surface or in underground workings; less common is injection into underground aquifers. The consequence of the excavation of open pits and other mining-related disturbances is that sulfide minerals previously isolated from the atmosphere are exposed to oxygen.

Sulfide Minerals

Unlike other mining methods, such as smelting, biomining does not require large inputs of energy and does not generate harmful emissions, such as sulfur dioxide (Orell et al., 2010; Rawlings, 2005). However, the time it takes for these processes to solubilize metals can span years ( Konishi, Asai, Tokushige, & Suzuki, 1999 ; Rohwerder, Gehrke, Kinzler, & Sand, 2003 ).
