Salt

Salt is a mineral substance composed primarily of sodium chloride (NaCl), which is essential for human and animal life. It is one of the oldest and most widely used commodities in the world, with a rich history dating back thousands of years. Salt was once so valuable that it was used as currency, and wars were fought over control of salt mines.

​

Today, salt is produced in many different ways, including mining, evaporation from seawater, and extraction from underground brine deposits. It is used for a variety of purposes, including food preservation, seasoning, and flavoring, as well as in the production of chemicals, textiles, and other industrial products. While salt is readily available and relatively inexpensive, it remains a vital commodity that is essential for life and commerce around the world.
