Calcium Carbonate, is one of the commonest mineral combination to be found on Earth. It is estimated that the mineral accounts for as much as 14% of the Earth's crust and is formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. From the mineralogical point of view, calcium carbonate falls into three structurally different groups: the calcite group, the aragonite group, and the dolomite group.
Limestone is generally used as a generic term which designates a compacted sedimentary rock made of calcium carbonate. It is often used as a synonym for natural calcium carbonate.
Marble is a metamorphic rock, which is the result of a re-crystallization process of limestone, under conditions of high pressure and temperature. True marble has a low porosity and may host calcite crystals of several centimeters.
All these minerals, when of the highest quality, are the source of industrial calcium carbonate.
