The Calcium

Calcium carbonate is an exceptional compound. The chemical formula CaCO 3 represents a raw material that exists everywhere in nature – whether dissolved in rivers and oceans, melted as "cold" carbonatite lava and solidified as a mineral, dripstone or as a parent material for whole mountain ranges.. Plants and animals need calcium carbonate to form their skeletons and shells, and even modern ...
