It's all about SALT!!!!!

What is salt?

Salt is Common salt, or sodium chloride, is the chemical compound NaCl. Salt occurs naturally in many parts of the world as the mineral halite and as mixed evaporites in salt lakes.

How is salt made?

How is salt made?

Salt is present in the rocky under layers of the Earth's surface and can be extracted through mining. These large deposits of salt are the result of ancient underground waterways that have long since dried up.

Rock salt is extracted through dynamite, similar in fashion to the mining of any other mineral. Once it is brought to the Earth's surface, it is crushed and used for industrial and other non-food purposes. This type of salt contains many minerals and other impurities.

Hydraulic mining of salt involves pumping water below the Earth's surface to dissolve salt deposits and create a salt brine. This brine is then pumped to the surface and evaporated to create salt. The salty brine may be treated prior to evaporation to reduce mineral content, yielding a nearly pure sodium chloride crystal. This method is inexpensive, has a high yield, and produces a very clean salt. Most table salt is produced with this method.

Why is iodine added to salt?

Iodine first began being added to salt commercially in the United States in 1924 by the Morton Salt Company at the request of the government. This was done as a response to the fact that there were certain regions in the U.S., such as around the Great Lakes and in the Pacific Northwest, where people weren’t getting enough iodine in their diets due to it not being prevalent in the soil in those regions. Among other problems, this caused many people to develop goiters (swelling of the thyroid gland, also sometimes spelled “goitre”)
