Icy sidewalks and roadways can lead to disasters. Wintertime slick surfaces can cause a variety of problems, from a simple slip to a major car accident. To prevent property damage,injury or death it's important for surfaces to be de - iced. This is usually don't by distributing sand,chemical de- icers or salt over the ice. Of all these three,salt is the most common.

The rock salt used on roads is the sane salt that is used on your dinner table. The larger salt pieces are typically ground down to finer crystals before being placed on your supermarket shelves. Salt is collected by underground salt mines and then processed, packaged and distributed. The largest salt mining company in the United States,American Rock Salt, produces 10,000 to 18,000tons of salt each day.
