How Is Rock Salt Made?
From Salt Water Rock salt deposits and mines typically form when salty water evaporates. The dissolved water contains sodium and chloride elements that are left behind, forming rock crystals. This naturally occurs in evaporated lake beds, bays and anywhere else that salt water can quickly collect and evaporate, depositing its minerals in the process. The Pacific, Atlantic, Indian and Arctic oceans have naturally created rock salt deposits, although they are not easily accessible and, thus, typically disappear after they’re disturbed or displaced by other elements such as flooding, heavy rains or high winds. Commercial Salt Mines Rock salt deposits exist throughout Australia, Europe and North America. These deposits can occur as deep as two or three miles underground, meaning that miners must oftentimes dig past the bottom of lakes and bays to reach this salty core. Some of the mining operations are so large and intricate that an entire system of buses is necessary to take people in and
