While rock salt is the most affordable and commonly used chemical to de-ice roads, sand also may be used. Other chemicals are also available. Most of these other chemicals are more commonly used for sidewalks or driveways. Each chemical, including road salt, has pros and cons.
A large amount of the comercially mined rock salt is prepared for human consumption. Rock salt is also applied to road beds in cold climates to help reduce the freezing point of water on the road, thereby allowing it to not freeze-over at 0 deg. C (although I have no first-hand knowledge of this since I live in Hawaii). 5. why is it important?
One of the main sources of table salt is the mineral halite or rock salt. Halite is mined. The minerals in mined salt give it a chemical composition and flavor unique to its origin. Rock salt commonly is purified, since halite occurs with other minerals, including some that are considered toxic.
Salt: Salt, also called sodium chloride, mineral substance of great importance to human and animal health, as well as to industry. The mineral form halite, or rock salt, is sometimes called common salt to distinguish it from a class of chemical compounds called salts. Learn more about salt in this article.

Most rocks are composed of minerals. Minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition. Of course, the minerals found in the Earth's rocks are produced by a variety of different arrangements of chemical elements.
The Khewra salt mine is a massive deposit of halite near Islamabad, Pakistan. Salt domes are vertical diapirs or pipe-like masses of salt that have been essentially "squeezed up" from underlying salt beds by mobilization due to the weight of overlying rock. Salt domes contain anhydrite, gypsum, and native sulfur, in addition to halite and sylvite.
