What is Rock Salt?
Rock salt, also known as halite, forms from the remains of ancient bodies of water in the rocky layers of the Earth’s crust. Rock salt, often known as ‘halite’ in the industry, is an unpolished mineral form of sodium chloride used to make table salt. The evaporation of enormous saltwater reserves such as oceans or lakes resulted in the formation of rock salt mines. These mines are around 1,200 meters (3,937 ft) or deeper below sea level.
