Limestone is a common sedimentary rock composed primarily of the calcium carbonate (CaCO₃). Limestone constitutes approximately 10 percent of the sedimentary rocks exposed on the earth’s surface.
Either limestone or marble may be used as the basis for crushed or ground calcium carbonate. Ground calcium carbonate, commonly referred to as GCC, and 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.
We manufactures crushed and ground limestone products at two of the performance mining plants.
At Minya Carbonate Company high brightness limestone from our quarry (size from 3 mm up to 45 micron) are ground into products which range in size from 36 micron to 2 micron.
GCC products are used in the whole variety of applications for limestones – building products, paints, plastics, agriculture, glass, animal feed, and paper, among others.
