Calcium Carbonate (GCC&ACC)

What is Calcium Carbonate (GCC & ACC)?

Calcium Carbonate is a naturally occurring mineral product derived from high-purity limestone, marble, or chalk deposits, produced by mechanically crushing, grinding, and classifying calcium carbonate-rich rocks into fine powders of controlled particle sizes.

GCC is one of the most widely used industrial minerals globally due to its versatility, cost-effectiveness, high whiteness, and excellent physical properties serving as a functional filler, extender, and performance-enhancing additive across numerous industries.

GCC & ACC is produced through mechanical processing of natural limestone not synthetic precipitation making it the most cost-effective CaCO₃ form for industrial use.

Frequently Asked Questions

Common questions from our B2B customers about Calcium Carbonate (GCC&ACC)

What is Calcium Carbonate (GCC&ACC)?

Calcium Carbonate (GCC&ACC) is a naturally occurring mineral produced by mechanically crushing and grinding high-purity limestone or marble. It is widely used as a functional filler and extender in industries including plastics, paints, rubber, paper and construction. GCC$ACC is valued for its high whiteness, chemical inertness, and cost-effectiveness.

What is the difference between GCC and PCC?

GCC&ACC (Calcium Carbonate) is produced by mechanical grinding of natural limestone cost-effective with a broader particle size range. PCC (Precipitated Calcium Carbonate) is synthetically manufactured giving better particle size control and higher surface area. For most industrial filler applications, GCC$ACC offers superior cost-performance, particularly for plastics, rubber, and construction.

What mesh sizes are available?

We supply GCC in 200 Mesh , 300 Mesh , 400 Mesh , 500 Mesh, D97µm,D20µm,D12µm,D8µm,D6µm,D4µm standard grades. Custom particle size distributions and surface-treated (stearic acid coated) variants are available on request.
