Utilization of Calcium Carbonate (Clam Shell)
- The clam shells (Mercenaria mercenaria) were ground and sieved with (-150+200mesh) screen. The elemental compositions of clam shells powder were determined by Energy Dispersive X-Ray Fluorescence (EDXRF) method. In this research work, calcium chloride, calcium sulphate dihydrate (gypsum) and calcium sulphate hemihydrates (plaster of paris) were prepared from clam shells powder. Determination of the optimum conditions for the conversion of clam shell to calcium chloride, calcium sulphate dihydrate and calcium sulphate hemihydrate were conducted using different parameters such as various amount of acids, reaction times and temperatures and also various salting-out agents. The compounds and elemental compositions of prepared calcium chloride, calcium sulphate dihydrate and calcium sulphate hemihydrates were determined and compared with that of the commercial products.
