First of all , The product of salt  has different types. The production of our salt is based on industrial salt.

  • In 2013, total world production of salt was 264 million tonnes
  • the top five producers being China (71 million)
  • the United States (40 million)
  • India (18 million)
  • Germany (12 million)
  • Canada (11 million).
 So, Salt is present in vast quantities in seawater, where it is the main mineral constituent.
Almost salt mounds in Salar de Uyuni, Bolivia The manufacture of salt is one of the oldest chemical industries.
as a result, A major source of salt is seawater, which has a salinity of approximately 3.5%. This means that there are about 35 grams (1.2 oz) of dissolved salts, predominantly sodium (Na+) and chloride (Cl−) ions, per kilogram (2.2 lbs) of water. So, The evaporation of seawater is the production method in marine countries with high evaporation and low precipitation rates.

production of salt:

above all, salt extracted from the vast sedimentary deposits which  laid down over the millennia from the evaporation of seas and lakes.  In either case, the salt may be purified by mechanical evaporation of brine. More recently, the process perform in pans under vacuum. as a result The raw salt is refined to purify it and improve its storage and handling characteristics. consequently, This usually involves re-crystallization  is treated with chemicals that precipitate most impurities (largely magnesium and calcium salts). So, The Ayoreo, an indigenous group from the Paraguayan Chaco, obtain their salt from the ash produced by burning the timber of the Indian salt tree (Maytenus vitis-idaea) and other trees.
