The essential components of rock salt, sodium and chlorine are essential elements for the operation of a large number of modern industries. Rock Salt as use in the oil industry, salt is used to increase the density of mud and soil, which creates a more safe and efficient drilling rig. Although salt may not be used extensively in off-shore drilling, enormous amounts of salt are required to facilitate drilling on land. Pharmaceutical companies also use salt in the process of making capsules, as well as the production of saline solutions, which have widespread secondary uses. Saline solutions are not only useful for contact solution, but also for intravenous formulas. Salt use by the medical and pharmaceutical companies accounts for a large percentage of the total industrial salt usage. Chemical production relies heavily on salt as well, as industrial salt is used as filler for detergents and solvents, causing the chemical to be more rapidly dissolved in water. Since salt separates many of the components required for making soap, chemical industries include large amounts of industrial salt in the process of making soap.

Solar ponds and other energy producing facilities require large amounts of salt to maintain a necessary salinity, adding to the application of industrial salt as an energy producer.

Since Rock salt is relatively cheap, available in large quantities in Pakistan, rock salt and industrial salt come into increasing demand with increased availability of solar energy. Clearly, industrial salt has widespread applications.

One of the most important applications of Rock Salt is for use in water treatment. In every country water supplies contain a high percentage of calcium and magnesium, which are very harmful for the life of equipment components and products requiring the use of this water. To avoid this, in the market there are many water treatment systems that use it as a raw material. This use is essential to maintain the efficiency of resins that help to provide us with softer water. This water will be better to keep the clothes clean and smooth, leaving hair softer and easier to comb, reducing the costs of using soap, avoiding mineral residue buildup in pipes which could block piping systems, improving the taste of water for cooking or preparing coffee and tea, reducing the cooking time of food, avoiding long-term health problems in human physiological systems and being available for use in ironing systems instead of distilled water. Also, most of the dishwashers sold in the market recommend the use of rock salt to improve their performance. It definitely improves the quality of domestic water.
