Abstract
A continuous process for obtaining calcium carbonate, comprising the steps of (1) continuously moving a mixture of calcium hydroxide and a first aqueous solution containing carbonate through a reaction zone to react said calcium hydroxide with not more than 80 % by weight of said carbonate to form calcium carbonate, (2) continuously removing fluid from the mixture leaving said reaction zone to form a filter paste, (3) contacting said filter paste with a second aqueous solution containing alkali metal carbonate, to complete, the conversion of calcium hydroxide to calcium carbonate and forming alkali metal hydroxide and removing alkali metal hydroxide from said paste during said contacting operation, and (4) washing the resulting calcium carbonate with water .
