Rock salt also known as halite is present in the rocky under layers of the Earth's surface and can be extracted through deep-shaft mining.

These large deposits of salt are the result of ancient underground waterways that have long since dried up. Rock salt is extracted through dynamite, similar in fashion to the mining of any other mineral. Once it is brought to the Earth's surface, it is crushed and used for industrial and other non-food purposes.

This type of salt contains many minerals and other impurities. While the ocean is a natural salt brine, hydraulic mining or solution mining of salt involves pumping water below the earth's surface to dissolve salt deposits and create a salt brine. This brine is then pumped to the surface and evaporated to create salt. The salty brine may be treated prior to evaporation to reduce mineral content, yielding a nearly pure sodium chloride crystal. This method is inexpensive, has a high yield, and produces a very clean salt.

Most table salt is produced with this method. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile.
