There are three common processes for the production of synthetic PCC (Sezer, 2013; and Bilen, 2010): 1) lime soda process (Kraft pulping method, Eq. 1); 2) calcium chloride process (Eq. 2), and 3) carbonation process (Eq. 3): Ca(OH) 2 + Na 2 CO 3 ↔ CaCO 3 + 2NaOH (1) CaCl 2 + Na 2 CO 3 ↔ 2NaCl + CaCO 3 (2)

2015-10-13 composition of calcium carbonate inside the cockle shell obtained from these three areas is up to 98%; that is later supported by Mohamed et al. (2012) in their findings. This proves that cockle shell is a good alternative to limestone in producing calcium chloride as far as calcium carbonate is concerned.
