Wyoming Mining Association: Trona Mining
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.
