How is Calcium carbonate formed? - innovateus.net

How is calcium carbonate manufacture? The manufacture of Calcium carbonate on a mass industrial scale is done by mining deposits of natural ores of carbonate viz. limestone from rocks. Alternatively through synthetic preparation, crude Calcium Oxide (CaO) is allowed to react with water to produce Calcium Hydroxide (Ca (OH) 2).
