Calcium carbonate is extensively utilized across various industries, including paper, plastics, paints, and coatings, serving primarily as a filler and, due to its distinctive white color, as a coating pigment. In the paper industry, it is globally recognized for its superior brightness and light scattering properties, making it a cost-effective filler for producing bright, opaque paper. This filler is introduced at the wet-end of paper manufacturing processes, ensuring that the resultant paper exhibits enhanced brightness and a smooth texture. In the realm of paints, calcium carbonate can constitute as much as 30% of the total weight, functioning as an effective extender. Furthermore, this mineral is widely employed as a filler in adhesives and sealants, underscoring its versatility and importance in various applications.
