Production of precipitated calcium carbonate from calcium …
In the lime soda process, calcium hydroxide is reacted with sodium carbonate to produce a sodium hydroxide solution, from which the calcium carbonate is precipitated. This process is commonly used by alkali manufacturers, for whom sodium hydroxide recovery is the main objective, and the coarse PCC produced is only a by-product.
