Salt accounts for about 3.5 percent of the world’s oceans. It is naturally produced when shallow ponds and bays dry up in the sun and the wind and large salt crystals are left behind where the salty water once was. Sea water contains many salts mixed in it. One of them is common salt, when sea water is allowed to stand in shallow pits, water gets evaporated by sunlight and slowly turns into water vapor. In a few days, the water evaporates completely leaving behind the solid salts. Common salt is then obtained from this mixture of salts by further purification.Today there are three main methods for obtaining salt:
Evaporation from sea water, Mining salt from the earth and Creating salt brines.
Salt is an example of a mature market for an abundant commodity. With a predictable market and no way to improve the product what happens is that profit margins are kept low and the market gets dominated by large suppliers.
Food salt is comparatively a small market and the price is so cheap that it would scarcely generate more than a few dollars per household per year.
