Calcium Carbonate

Ground Calcium Carbonate (GCC) is a mineral derived from natural limestone, primarily composed of calcium carbonate (CaCO₃). It appears as a fine white powder with high purity, typically containing over 95% calcium carbonate. Due to its alkalinity, GCC serves as a valuable additive in various industries. With a density of approximately 2.7 g/cm³ and high brightness, it is particularly useful where color and appearance are important. The production process involves milling limestone through a series of crushing, grinding, and classifying stages to achieve the desired particle size. The quality of GCC largely depends on the source of the limestone, with major production regions including the United States, Europe, and Asia.
