Heavy calcium carbonate (GCC) is mechanically ground from natural minerals. ⚙️ Its particles are irregular, larger in size, and have lower whiteness and purity, making it a cost-effective choice 💰. GCC is mainly used in plastics, rubber, and coatings 🏭 to reduce costs, improve processing, and enhance surface smoothness and hardness.

Light calcium carbonate (PCC) is produced chemically 🧪, with fine, uniform particles, higher whiteness, and higher purity. It is widely used in plastics, paper, food, and pharmaceuticals 📄🍽️💊, improving plastic toughness, paper whiteness and smoothness, and serving as a calcium supplement or pharmaceutical intermediate.

✅ Summary: GCC → cost-sensitive applications with lower purity.
✅ PCC → high-end products requiring better appearance & performance.
