Types of salt with regard to the manner of its production
In view of the manner of production, the so-called evaporated, stone and sea salts are known today. Salt can be industrial or traditional.
Evaporated salt is produced through dissolution of salt ore, by dissolution of sea or stone salt, or with condensation of sea salt in condensation basins especially prepared for these purposes and its eventual recrystallization in a factory. Stone salt is dug in mines as an ore. Sea salt is made with the aid of the sun and wind through condensation of sea water in evaporation basins and through crystallization in crystallization basins. Sea salt can also be unrefined and refined. Through its refining, as pure as possible NaCl is obtained. Traditional salt is manufactured in a similar manner as unrefined salt, except that the surface areas of crystallization basins are by few times smaller. Salt is made during higher concentrations of brine. It is raked with manual appliances called gaveri.
