Rock salt (halite) is the salt left behind by primordial oceans millions of years ago when lagoons dried out. These layers of salt were covered by rock formations and they are now located underground or inside mountains. Rock salt refers to the dry salt extracted from saliferous rock layers with the help of mining methods.

Halite, commonly known as table salt or rock salt, is composed of sodium chloride (NaCl). ... Many rock salt mines use the room-and-pillar method of underground mining in which the resource is extracted, leaving ‘pillars’ of the material untouched, which creates ‘rooms.’ ...

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.

Halite salt (NaCl) can be mined in two different ways: as a solution or in dry mining (see map below). In solution mining, fresh water is injected through a pipe into deep shafts that end in the salt beds, and salty water (brine) is drawn upward and dried, to recrystallize the salt. Or, salty brine found in shallow wells can simply be pumped to ...

Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.

The room and pillar mining method leaves considerable rock in place as a natural support. Ventilated by fans that circulate fresh air, the rooms and tunnels are about 100 feet below the surface. Diesel-operated machines drill a specific pattern of blast holes in the end of each working side tunnel or "bench."
