We will start with Soda Ash Manufacturing Process; Sodium carbonate (Na2CO3) also known as washing soda or soda ash, is a sodium salt of carbonic acid. Most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the mono hydrate. Sodium carbonate is domestically well known as a water softener.

Precipitated calcium carbonate (PCC), is made by first hydrating high-calcium quicklime, and then reacting the resulting slurry or "milk-of lime" with carbon dioxide. The resulting product is extremely white and has a uniformly small particle size. It has numerous uses, most notably in the paper industry.
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 is purer than ground calcium carbonate and has different (and ...
