Carbonate binders by "cold sintering" of calcium carbonate
The solubility of calcium carbonate (limestone) particles depends on the amount of CO2 dissolved in the water, which is a function of temperature and the pressure of CO2 that is in equilibrium with water. At a constant temperature, increasing CO2 pressure increases the solubility of CaCO3, and decreasing CO2 pressure favours the …

Purification depends on the source; how impure it is to start with. It is generally difficult to separate magnesium carbonate from calcium carbonate, and given that limestone and aragonite as well as dolomite ($ce{CaMg(CO3)2}$) are taken out of the ground (i.e. are 'dirt' cheap) there's usually no need.

Carbonate Rocks – Geology is the Way
Identification of carbonate rocks Limestone is easily recognizable because it fizzes in contact with HCl (hydrochloric acid), due to the reaction:. CaCO 3 + 2HCl ⇌ CO 2 + H 2 O + CaCl 2. Dolostone does not fizz on a 10% diluted HCl solution, but can fizz if the solution is put in contact with a dolomite powder or if a less diluted solution (around 30%) is used.

Calcium Carbonate
Abstract. Calcium carbonate is a chemical compound with the formula CaCO 3 formed by three main elements: carbon, oxygen, and calcium. It is a common substance found in rocks in all parts of the world (most notably as limestone), and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells.
