Ground Calcium Carbonate (GCC) Production

Ground calcium carbonate (GCC) is typically produced through a grinding process that takes mined limestone and grinds it into smaller particles through several stages.

The limestone mining process produces large aggregate boulders which are then processed through a series of crushers to an average size of 15 mm-50 mm. This finer material is then sent through the milling process which produces smaller limestone particles that form a powder. The calcium carbonate powder is then collected and packaged for use.

Chemical Composition And Features of Ground Calcium Carbonate

Calcium carbonate has the chemical formula CaCO3, and it comprises more than 4% of the earth’s crust and is found throughout the world. These abundant minerals are commonly found in the natural forms: chalk, limestone, and marble. Calcium carbonate is produced by the sedimentation of the shells of small, fossilized snails, shellfish, and coral over millions of years. These fossilized remains that now make up a percentage of the earth’s crust can be both sedimentary rock and metamorphic rock. The sedimentary rocks that most often contain calcium carbonate are chalk and limestone, whereas marble is a metamorphic rock. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness, and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to humans.

While some of the purest ground calcium carbonates can be obtained naturally from marble, an ultra-pure form can be produced by exposing carbon dioxide to a solution of calcium hydroxide (the hydrated form of calcium oxide). Calcium carbonate is derived from the mixture of these two substances which forms a grade of product called "precipitated calcium carbonate,” otherwise known as PCC.

Due to the chemical composition of calcium carbonate, it is used in many products including paper and plastic fillers, paints, and other industrial applications. Particle size, chemical purity, and color may be the determining factors in whether or not GCC is the appropriate choice for a specific application.

Ground calcium carbonate is CaCO3 that has been crushed and ground for applications that require a fine powder.

FAQs

How Is Ground Calcium Carbonate Made?
GCC, as the name implies, involves crushing and processing limestone to create a powdery-like form graded by size and other physical properties and mechanical properties for many different industrial and pharmaceutical applications.

What Is Calcium Carbonate Powder Used For?
Calcium carbonate can be used across many industries including the paper industry, medical industry, food industry, and construction industry. Calcium carbonate products and byproducts can also be used for waste treatment, grinding aids, animal feed, and more.

What Is The Difference Between PCC And GCC?
Both precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) are ground limestone products. PCC ground limestone products are made by hydrating high-calcium quicklime and then reacting the resulting slurry with carbon dioxide. Ground calcium carbonate (GCC) is simply the ground and powdered form of pure calcium carbonate.
