Production of Precipitated Calcium Carbonate

01/01/2014  Sodium hydroxide can be produced by reacting calcium hydroxide with sodium carbonate. Calcium carbonate is generated as a by-product, but since this material contains substantial amounts of impurities such as gypsum, it has limited applications. In general, it is either used as a raw material for cement or burned in a lime kiln to regenerate lime. Some fractions are also disposed as waste.
