Salt/Halite Mining Process. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.
