Salts that are harvested from rock deposits were formed by the evaporation of ancient seas. Rock salt can be mined directly, as shown in SF Fig. 2.7, or acquired by pumping a solvent, like water, into the deposit. Water dissolves the salt, forming a salty brine solution. The salt is then harvested by dehydrating …

Salt/Halite Mining Process. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.Web

In this process, three mining chambers, each up to 40 meters high, are built one above the other, in which the salt is blown off in vertical mining discs. The chambers, which are up to 100 meters long and 20 meters wide, are supported horizontally and vertically by layers of salt rock, so-called pillars, so that they are permanently stable.Web

The room and pillar method of mining is employed in all salt mines in Michigan, Ohio, and Ontario. The rooms vary in width from 30 to 60 ft and in height from approximately 17 to 40 ft. Pillar size is adjusted so that the extraction or recovery will attain a maximum of 70%. Actual mining is confined completely to the salt bed.Web

Rock salt is a sedimentary rock primarily composed of halite. Halite is a mineral of sodium chloride (common salt), NaCl. Rock salt is usually white or colorless. However, impurities in the rock salt can make it appear light blue, pink, purple, yellow, orange, or gray. Colorless salt is rated the purest as it doesn't contain any impurities.Web
