Solution Mining
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.
