The Solution Mining Research Institute (SMRI) is a research and educational organization focused on solution mining.
SMRI views solution mining as mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns. The caverns are created by pumping out the saturated 'brine' while pumping in fresh water as a controlled production process. The minerals are then recovered from the saturated fluid by recrystallization. Completed salt caverns are commonly used for underground storage of natural gas, crude oil, other hydrocarbons or chemicals, and are now viewed as a possible energy storage solution for green energy! The caverns used for strorage are more valuable than the minerals produced during cavern development.
