Jun 01, 2012 A novel process for precipitated calcium carbonate production and carbon dioxide mineralization is studied. The process consists of two steps; firstly calcium is selectively extracted from steelmaking slags with an ammonium salt solution, secondly the dissolved calcium is allowed to react with carbon dioxide and is thus precipitated as calcium carbonate.

Abstract. Discreet nano-sized precipitated calcium carbonate was prepared by a simple solution mixing process, in which sodium carbonate solution was injected into calcium chloride solution containing calcium hydroxide. The morphology, size, and structure of the as-prepared precipitated calcium carbonate and intermediate products were examined.
