Sea Salt Used In Chemical Industry

Sea Salt Sea salt is the name given to salt extracted through seawater. We collect sea salt by moving the brine (seawater) into PVC-floored salt evaporation ponds, and extracting salt from the evaporite. The hot and dry climate of Pakistan allows us to evaporate water from the brine solely through solar energy. The extracted salt contains numerous impurities, and must first by purified. We can provide sea salt processed for a number of uses, including the following: Industrial Grade Salt Sea salt has hundreds of industrial applications. It is very widely used in chemical industries, for example, the Chlor-Alkali industry, which uses chiefly salt to manufacture chlorine and caustic soda. Chlorine and caustic soda are used further in the manufacture of paper. It is also used as a water softener. Soft water can more economically use soap and detergent, and is therefore ideal for cleansing purposes. Rubber manufacturers use salt to separate rubber from latex. It is used in the metal industry to remove impurities from metal. We produce A and B Grade Sea Salts for such industrial uses. Another major use of salt is de-icing, removing ice from a surface. Although rock salt is the more common type of salt for this purpose, sea salt is also perfectly suited to perform the task. This works by spreading diluted salt over the frozen surface. Since salt water has a lower freezing point than pure water, ice melts away as soon as it absorbs salt. We produce a C Grade Sea Salt for de-icing purposes.
