Calcium Carbonate Essential Minerals Association
Calcium carbonate is one of the most useful and versatile materials known to man This family of essential minerals comprises more than four percent of the earth’s crust and is found worldwide It is produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years The most common forms of calcium carbonate are chalk, limestone, and Kaolin and calcium carbonate are both used as fillers or extenders, in other words they make something cheaperBy adding them the volume goes up and the cost per ton goes down What music to our ears!
