Industrial and Agricultural Salt
Only about 6% of the salt manufactured in the world is used in food. Of the remainder, 12% is used in water conditioning processes, 8% goes for de-icing highways and 6% is used in agriculture. The rest (68%) is used for manufacturing and other industrial processes, and sodium chloride is one of the largest inorganic raw materials used by volume.
Some of the major Industrial uses of Salt:
Oil and gas exploration - Salt is an important component of drilling fluids in well drilling. It is used to flocculate and increase the density of the drilling fluid to overcome high downwell gas pressures.
Textiles and dyeing - Salt is used as a brine rinse to separate organic contaminants, to promote “salting out” of dyestuff precipitates, and to blend with concentrated dyes to standardize them.
Metal Production - Aluminium, beryllium, copper, steel and vanadium.
Pulp and paper industry - Salt is used to bleach wood pulp.
Tanning and leather treatment - Salt is added to animal hides to inhibit microbial activity on the underside of the hides and to attract moisture back into the hides.
Rubber manufacture - salt is used to make buna, neoprene and white rubber types. Salt brine and sulfuric acid are used to coagulate an emulsified latex.
