The origin of salt
Rock Salt
The rock salt, also named "salt of quarry", is extracted from subterranean deposits developed down the ages.
The origin
The motions of the earth’s crust, during geologic eras, caused the development of real brackish lakes, or pelvis of seawater, like mountain range. Down to the centuries the water has slowly evaporated leaving stratifications of salt. From the stratifications that followed through the centuries new deposits of salt developed and sometime can reach the thickness of hundred of meters. The rock sea is utilised both for alimentary and industrial use.
Food industry use: working process
The alimentary rock salt is extracted by particular machinery named "continuous miner". Once extracted, it is crunched and reduced to different granulometries: fine, medium and coarse rock salt.
Industrial use: working process
The industrial rock salt can be obtained by springing the mines. The raw mineral is reduced in small fragments and later on in the granulometry requested.
