Ground Calcium Carbonate (GCC) | Minerals Technologies Inc.

Either limestone or marble may be used as the basis for crushed or ground calcium carbonate. Ground calcium carbonate, commonly referred to as GCC, is widely used as an industrial mineral. Three primary attributes: particle size, color and chemical purity define the quality of the GCC, and define the suitability of use for any given application.

Calcium carbonate is also very inexpensive because it is a fairly ubiquitous compound; in fact, it is the largest reservoir for carbon. Filtration with calcium carbonate should be relatively easy compared to other compounds because calcium carbonate does not clump when exposed to water (Zumdahl, 2000). Thus, these factors prompted the use of calcium carbonate in this study.
