Food salt

Sodium chloride or common salt (sodium chloride, NaCl; as used name "Sodium chloride", "table salt", "rock salt", "table salt" or simply "G"), - food product. The crushed form, is a colorless crystals. Sol natural (sea) descent almost always has impurities of other inorganic salts, which may give it shades of different colors (usually gray or brown). It is produced in different forms: coarse and fine grinding, clean, iodinated, nitrite, and so on. Depending on the purity is divided into grades: extra, higher, first and second.

production technology:

deposited lump salt, which is extracted from the "salt waterfalls" by natural evaporation of sea water from the cavities;

sedimentary salt, which is extracted from depths of salt lakes or in salt lakes cave. Extraction sedimentary salt is carried out in the warm season in areas with a suitable climate by natural evaporation of the brine in sedimentary basins artificial planar. In cold climates the freezing method used;

rock salt, which is extracted by the development of mines. Is not exposed to heat and water treatment;

evaporated salt that is produced by evaporation of brines (brines from natural groundwater or obtained by pumping water through boreholes reservoir rock salt).
