Salt Cavern - an overview | ScienceDirect Topics

Salt caverns are artificial cavities in underground salt formations, which are created by the controlled dissolution of rock salt by injection of water during the solution mining process. Geometrical volumes of a few 100 000 m 3 , and up to 1 000 000 m 3 and more in individual cases, can be achieved depending on technical specifications and ...

How salt is made - material, used, processing, procedure ...

Rock salt is simply crystallized salt, also known as halite. It is the result of the evaporation of ancient oceans millions of years ago. Large deposits of rock salt are found in the United States, Canada, Germany, eastern Europe, and China. Sometimes pressure from deep inside the Earth forces up large masses of rock salt to form salt domes.
