In Sicily a salt deposit of 5 million years ago by deposition of salt when seawater evaporated away leaving large quantities of dissolved salt as precipitate.
During this period the Mediterranean Sea was undergoing a cycle of partly or nearly complete desiccation, which geologists call the Messinian Salinity Crisis.
In Porto Empedocle, the port of Agrigento, from the pier realized with the stones of the valley of the temples, large cargo ships, loaded with road salt for de-icing, leave for US, Norway, Sweden, Finland, Slovenia, Croatia and Northern Italy too.
In 2016 546,630 tons of road salt for de-icing shipped in total, 132,000 tons in the US.
The ships charge up to 20,000 tons of salt.
A visual underground journey in Petralia, Racalmuto and Realmonte, the only salt mines of Sicily.
In Petralia the salt extracted it’s just for food, thanks to its incredible purity and the salt extracted in Petralia is packaged directly on site and sees the light, for the first time after millions of years, only once the boxes have reached the house of the consumers.
