Carbonate minerals and their relative stability Calcite, crystallizing in the rhombohedral crystal system is the thermodynamically stable phase of calcium carbonate. Aragonite, calcite''s orthorhombic polymorph, is about 1.5 times more soluble than calcite. Magnesian calcite is an important sub-group of carbonates that occurs as skeletal components and marine cements. …

Introduction Seawater desalination has become an essential solution for providing fresh water in regions where it is scarce. However, desalinated water often lacks essential minerals, making it unsuitable for direct consumption. Benefits of Using Calcite, a naturally occurring form of calcium carbonate (CaCO3), plays a crucial role in the remineralization process, ensuring that …

Limestone Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Dolomite, CaMg (CO3)2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. Limestone is found in our region Afar around Aba’ala.
