Ground Calcium Carbonate Manufacturing Process

Ground Calcium Carbonate (GCC), a crucial material in various industries, undergoes a comprehensive manufacturing process. This article details each step, ensuring clarity in how manufacturers transform raw limestone into fine, ground calcium carbonate powder.

Exploration and Extraction of Limestone

Identifying Limestone Deposits

Professionals conduct geological surveys to locate limestone deposits. They use advanced equipment to measure the quality and quantity of the limestone, ensuring it's suitable for calcium carbonate production.


Workers use heavy machinery to extract limestone from the earth. They employ drills, explosives, and cutting tools to efficiently and safely remove large blocks of limestone.

Crushing and Grinding

Primary Crushing

The extracted limestone undergoes initial crushing to reduce its size. Large crushers break down the rocks into smaller pieces, typically less than 30 cm in diameter.

Fine Grinding

Next, the smaller limestone pieces go through fine grinding. Mills pulverize these pieces into a fine powder. The particle size of the final product usually ranges from 5 to 10 microns, essential for high-quality GCC.

Chemical Treatments and Coating


To increase purity, manufacturers treat the ground limestone with chemicals. This step removes impurities and enhances the quality of the GCC.


For specific applications, a coating process follows. Manufacturers apply substances like stearic acid to the GCC to alter its properties, improving its compatibility with various industrial processes.

Quality Control and Packaging


Quality control teams conduct rigorous tests. They measure particle size, purity, and other critical parameters to ensure the GCC meets industry standards.

Packaging and Distribution

Finally, the GCC gets packaged for distribution. Manufacturers use bags or bulk delivery systems, depending on customer needs and order sizes.

Calcium Carbonate Powder Production Line
