The paper industry is the most potential market for light calcium carbonate. Light calcium carbonate as a papermaking filler has the following advantages: high light shielding, high brightness, can improve the whiteness and light shielding of paper products; high expansion, can make paper mills use more fillers and greatly reduce the cost of raw materials; fine particle size, uniform, more uniform products, smooth; high oil absorption value, can improve the expected firmness of colored paper.

Can be used for coating processing paper raw materials, especially for high-grade copper board paper. Because of its good dispersion performance and low viscosity, it can effectively improve the whiteness and opacity of the paper, improve the smoothness and softness of the paper, improve the absorption performance of the ink, and increase the retention rate.

Light calcium carbonate is mainly used as the filler of paper in papermaking. In order to ensure the strength and whiteness of paper and reduce the cost, a large amount of calcium carbonate is added to the paper. The extensive use of calcium carbonate in the paper industry is based on the international paper industry from acidic papermaking process to alkaline or neutral paper process, so that a large number of cheap calcium carbonate can be used instead of the previous talc and porcelain clay.
