Ground calcium carbonate, also known as GCC (Ground Calcium Carbonate), is extracted from naturally occurring limestone. 
Cemix has raw material sources of exceptional purity in Uzbekistan.
The limestone is crushed in a complex process and ground into powders of different grain sizes. The end product is a white powder with excellent optical and physical properties.

1. Improved whiteness and opacity: GCC gives the paper excellent whiteness and high opacity. This is particularly important for the production of high-quality printing papers and writing papers, as it improves legibility and color brilliance.

2. Cost efficiency: by using GCC as a filler, production costs can be reduced as the amount of more expensive fibers is reduced without compromising the quality of the paper.

3. Improved printing properties: ground calcium carbonate ensures uniform structures and smooth surfaces, which enables better ink absorption. This results in sharper prints and better color reproduction.

4. Environmental friendliness: GCC is more environmentally friendly than other fillers as it is extracted from natural sources and is fully recyclable. It also helps to reduce energy consumption in paper production.

5. Increase in paper strength: The use of calcium carbonate can improve the strength of the paper as it strengthens the bond between the fibers. This is particularly beneficial in the production of packaging paper.

Printing and writing papers such as offset printing paper and copy paper, where high opacity and whiteness are crucial for a high-quality end product.

GCC is also well suited for newsprint as it reduces costs while providing sufficient brightness.
In packaging paper and board, GCC is used to increase stiffness and strength and reduce production costs.

In wallpaper papers, GCC provides a smooth surface and increases opacity.

Specialty papers such as technical or art papers have special requirements in terms of surface quality and strength, some of which are achieved by using GCC. In other cases, PCC (precipitated calcium carbonate) is used.
