Solution Mining - MiningInfo

The chemical industry uses salt or "sodium chloride" as a basic raw material in many of their manufacturing processes. Salt saturated brine is sometimes produced by solution mining the rock salt from inside these underground salt domes. A large diameter borehole is drilled to about 4000 - 5000' deep using standard oil industry drilling methods.
