　　I. Preparation Methods of 2500-mesh Ultrafine Heavy Calcium Carbonate

　　2500-mesh ultrafine heavy calcium carbonate can be prepared by various methods. The following are some commonly used methods:

　　1. Wet preparation method: Natural limestone or lime is reacted to produce calcium hydroxide, which is then reacted with carbon dioxide to produce calcium carbonate. By controlling the reaction conditions and adding an appropriate amount of surfactant, ultrafine heavy calcium carbonate with a smaller particle size and good dispersibility can be obtained.

　　2. Dry preparation method: High-purity limestone or other calcium-containing minerals are crushed and ground, and then calcined at high temperatures to decompose into calcium oxide, which is then reacted with carbon dioxide to produce calcium carbonate. The calcium carbonate produced by this method has smaller and more regular particles.
