Salt is mined as a solid in shaft mines with depths of 500 to 2000 feet, in Michigan, Ohio, New York, Kansas, Louisiana, and Texas. 

Run-of-the-mine salt contains 98 to 99 percent NaCl. Over 25 percent of the world s salt is produced in the United States. 

Very extensive production of artificial brines is carried out along the U.S. Gulf Coast, principally in Texas and Louisiana, where huge domelike deposits of rock salt exist in readily accessible areas. Some of these domes are 4 miles in diameter and over 8 miles deep, containing over 100 billion tons of salt each. In order to mine salt efficiently and safely and to utilize the subsequent cavern for storage.
