Prior to the advent of the internal combustion engine and earth moving equipment, mining salt was one of the most expensive and dangerous of operations. While salt is now plentiful, before the Industrial Revolution salt was difficult to come by, and salt mining was often done by slave or prison labor. In ancient Rome, salt on the table was a mark of a rich patron (and those who sat nearer the host were above the salt, and those less favored were "below the salt"). Roman prisoners were given the task of salt mining, and life expectancy among those so sentenced was low. Roman soldiers were paid in salt, which is where the term "salary" comes from.

Even as recently as the 20th century, salt mining in the Soviet Union and Nazi Germany was performed by persons being punished.

Today most salt mines are operated by large multi-national companies like Cargill and Compass Minerals.
