炭酸カルシウム
高純度方解石・重質炭酸カルシウム (GCC) | 98.5%+ CaCO3
Quick Answer
What is Pakistan 炭酸カルシウム? 炭酸カルシウム sourced from Pakistan is a high-grade industrial mineral known for its premium quality, specifically 高純度方解石・重質炭酸カルシウム (gcc) | 98.5%+ caco3. Indus Minerals exports this material in bulk via Karachi Port to markets including UAE, Bangladesh, Saudi Arabia, Indonesia.
Indus Ores, Minerals & Resources exports high-purity Calcium Carbonate (CaCO3) sourced from the premier crystalline calcite and white marble belts of Khyber Pakhtunkhwa (Swabi, Buner, Nowshera, and Mohmand) and the high-calcium formations of Punjab and Sindh. Utilizing precision ball-mill and air-classification circuits, we supply both uncoated Ground Calcium Carbonate (GCC) and stearic acid surface-coated grades alongside raw crystalline calcite lumps.

よくあるご質問（FAQ）
What grades of Calcium Carbonate do you export from Pakistan?
We export three primary commercial grades from Pakistan: 1) Raw Crystalline Calcite Lumps (10mm–100mm, 98.5%+ CaCO3) for overseas grinding mills, 2) Uncoated Ground Calcium Carbonate (GCC) from 325 Mesh to 2500 Mesh (D97: 6μm–45μm) for emulsion paints, paper coating, and construction chemicals, and 3) Stearic Acid Surface-Coated GCC (800 Mesh to 3000 Mesh, D97: 5μm–15μm) engineered for rigid PVC pipes, cables, and polyolefin masterbatches.
Where are Pakistan's highest-purity Calcium Carbonate deposits located?
Pakistan's highest-purity crystalline calcite and white marble deposits are located in Khyber Pakhtunkhwa—specifically the Swabi, Buner, Nowshera, and Mohmand districts—which naturally yield 98.5% to 99.2% CaCO3 with brightness exceeding 96% and negligible iron content (<0.03%). High-volume industrial limestone and carbonate reserves are also quarried in the Attock/Margalla hills of Punjab and the Thatta/Dadu corridors of Sindh.
What is the advantage of Stearic Acid Coated Calcium Carbonate for plastics and PVC?
Surface modification with 1.0% to 1.5% food/industrial-grade stearic acid converts hydrophilic CaCO3 particles into a hydrophobic filler. This lowers oil and plasticizer absorption (down to 12–16 g/100g), prevents agglomeration during twin-screw extrusion, improves impact strength and surface gloss in rigid uPVC pipes and profiles, and allows higher filler loading without increasing melt viscosity.
How do you verify particle size distribution (D50 / D97) and whiteness before shipment?
Every production batch undergoes Laser Diffraction Particle Size Analysis (Malvern Mastersizer) to verify top-cut (D97) and median (D50) micron specifications, alongside spectrophotometer whiteness testing (ISO 2470) and chemical titration/XRF for CaCO3 purity. Pre-shipment composite sampling at Karachi Port is certified by SGS, Alfred H. Knight, or Intertek.
