What is Solution Mining? Solution mining is the process of extracting underground, water-soluble minerals (salt, potash, trona, etc.), through one or more drilled wells, by dissolving the minerals with water. As the water circulates, it dissolves the mineral and becomes saturated, the brine is forced up a separate pipe string to the surface.

The Solution Mining Process Solution mining is an alternative to mechanical excavation of salt ores (Richner et al. 1992). Since most waste components in solution mining are not soluble they are left behind to settle to the bottom of the expanding cavern, as the brine product is removed to a surface processing facility.
