<P> Salt is processed from salt mines , and by the evaporation of seawater ( sea salt ) and mineral - rich spring water in shallow pools . Its major industrial products are caustic soda and chlorine ; salt is used in many industrial processes including the manufacture of polyvinyl chloride , plastics , paper pulp and many other products . Of the annual global production of around two hundred million tonnes of salt , only about 6 % is used for human consumption . Other uses include water conditioning processes , de-icing highways , and agricultural use . Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency . As well as its use in cooking and at the table , salt is present in many processed foods . </P>
