Salt is a dietary mineral essential for animal life. It is composed primarily of sodium chloride. Salt is produced in different forms; they are unrefined salt or sea salt, refined salt or table salt and iodized salt.

Salt is a crystalline solid, white, pale pink or light grey in color. It is obtained by evaporation of sea water, usually in shallow basins warmed by sunlight.

It is also obtained from rock deposits.

Salt is used in more than 14,000 commercial applications other than in cooking. It is used in the manufacture of pulp and paper and setting dyes in textiles and fabric. It is also used in producing soaps and detergents and for making snow-covered roads safe in winter.

Salt plays an essential role in our daily lives.
