Rock Salt Type, Composition, Formation, Occurrence, Mining
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
