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's process basically takes limestone (CaCO 3) and salt Brine (2 NaCl) to produce sodium carbonate (Na 2 CO 3 ). And, you won't be surprised to find out that the main by-product of the Solvay process is calcium chloride. Of course the actual Solvay process is quite a bit more complicated than I can explain here.

Due to lack of supply, three quarters of worldwide production is produced synthetically. There are various methods, but principally, synthetic soda ash is made via the solvay process, which uses salt, limestone, ammonia, and hydrocarbon (coke/natural gas). Synthetic producers react ammonia with carbon dioxide and water to form ammonium bicarbonate.
