The calcium carbonate production rate by the rhodolith bed of QGI (CaCO 3 pr, expressed in g m −2 yr −1) was obtained using the equation below: CaCO 3 pr = 4/3 * π * Vit * A *d * {[R a + g) * (R b + g) * (R c + g)]
The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate).

Precipitated Calcium Carbonate (PCC)
Calcium Carbonate Production Cost Analysis 2021 Calcium carbonate is a chemical compound that is often found in rocks as the minerals calcite as well as in aragonite or most notably as limestone, which is a type of sedimentary rock composed primarily of calcite and is the primary component of pearls and the shells of several marine organisms like snails or eggs.

Since carbonate cake contains a large amount of calcium carbonate, it can be used for phosphate adsorption. Carbonatisation cake is formed in a very small particle size as a result of the reaction of dissolved calcium hydroxide with carbon dioxide in carbonatisation, and it may be an effective adsorbent due to its formation in a relatively basic medium.

Ground Calcium Carbonate
Calcium carbonate is a chemical compound of CaCO 3 which is formed up by three elements; carbon, oxygen and calcium. Natural calcium carbonate rocks are found throughout the world, the most typical forms are marble, limestone and chalk. The calcium carbonate rock could be extracted by blasting, crushing and grinding process.
