Calcium chloride is a naturally occurring compound produced worldwide and commercially sold for ice melting, snow melting, and dust control applications.
Typically when calcium chloride is found in nature, it is in a liquid form and always coupled with other mineral salts such as potassium chloride (potash), sodium chloride (salt brine), and magnesium chloride. These natural brines frequently provide the feedstock for the processes which produce calcium chloride as a by-product as the other minerals are removed and processed for their respective markets.
