Calcium carbonate is a type of chemical compound often found in rocks, minerals, and other natural formations. This material occurs in several forms, including calcite, aragonite, and vaterite, which are all crystalline forms of calcium carbonate. This is also the main component in limestone, marble, and chalk.
There are many industries that rely on calcium carbonate today. For example, in the construction and building industries here in North Carolina, limestone is used as a building material and in the production of cement and mortar. Calcium carbonate is also used in the food and beverage industry. For instance, it is used as a dietary supplement for providing calcium and as a food additive, as a food coloring agent, or as an anti-caking agent.
