Rock salt (Halite) was formed millions of years ago with the evaporation of sea water or salt lakes. The rock salt is then extracted from the underground deposits with various extraction techniques (grinding or explosions), depending on the destination of the product on the market.
Sodium chloride (NaCl) is found in abundance in nature and most of it is dissolved in sea water.
In the sea salt production tanks, the sea water, through a forced path in which the fractional crystallization is transformed into "salt" by natural evaporation.
The recrystallized or hyperpure boiling salt is extracted from underground deposits formed millions of years ago. The water is injected into the "salt bank" to create a cave where the brine is formed, then it is brought to the surface and purified. Subsequently, "recrystallization" will take place at the plant.
