Salt (NaCl) is a natural mineral made up of white cube-shaped crystals composed of two elements, sodium and chlorine. It is translucent, colourless, odourless and has a distinctive and characteristic taste. Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools.

Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
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. Other uses include Water conditioning processes, Industrial Chemicals, Food grade salt, De-icing highways, Paper manufacturing, Agricultural, etc.


Food Grade Salt

Table salt is pure salt that has been ground into fine particles. As salt tends to cake in humid climates, an anti-caking agent such as magnesium carbonate or calcium silicate is often added. Table salt is also available as iodized salt with 0.1 percent potassium iodide by weight. Because iodine ion is essential to thyroid gland function, the routine use of iodized salt ensures adequate iodine in the diet.

chemical Applications

The chemical industry is by far the largest consumer of salt. lt is the raw material for the production of chlorine (Cl) and caustic soda (sodium hydroxide, NaOH). Chlorine is an extremely effective disinfectant and an essential component in the chemical manufacture of various products like PVC.
Salt is also one of the raw materials used in manufacturing sodium carbonate (soda ash).


Rock salt is sprinkled on highways to melt ice. The lowest temperature at which salt can melt ice is −21°C (−6°F), at a concentration of 23 percent salt, and it works best when temperatures are at or slightly below freezing, 0°C (32°F).

Industrial application

In the form of Caustic soda & Soda ash Salt is one of the main ingredients for glass-making, pulp and paper industry, textiles, detergent and the chemical processing industry, waste and water treatment, petroleum additives, dyes and intermediates, etc.

Animal feed

Animals also need sodium and chloride for survival. Supplementing livestock rations with salt is a good way to maintain ideal weight gain thereby increasing yield and performance. Rock salt is enhanced with specific minerals such as cobalt, iron, copper, zinc, manganese, etc. The right salt intake ensures their growth, strong immune and reproductive systems.

water conditioning

Water is considered hard when it contains hardness ions (calcium & magnesium). The hard water causes mineral build-up inside water heaters, pipes, dishwashers, washing machines, and other water-using appliances. Through a process called ‘Ion exchange’, magnesium and calcium minerals (hard ions) and replace them with sodium (soft ions).
