We process calcium carbonate from pristine limestone and marble deposits with advanced grinding and air-classification technology.
Our CaCO3 is processed from carefully selected limestone and marble deposits in Rajasthan, ensuring brilliant whiteness (>97%), high purity (>99%), and stable chemistry.
Each batch is tested for purity, particle size, whiteness, and pH before dispatch. Our quality management system is independently audited.
Natural GCC, fine (10 micron), coarse, coated (stearic acid), and micronized calcite — we have the exact CaCO3 specification your process demands.
Our surface-treated coated grade is hydrophobic and organophilic — ideal for maximizing filler loading in PVC and polymer compounds without mechanical loss.
Since 2001, Raviraj Minerals has been a trusted raw material partner for India's leading paint, plastic, rubber, pharmaceutical, and construction companies.
We export to 25+ countries with reliable HDPE/PP bag packaging, SDS documentation, and logistics support for both sea and air freight.

About calcium carbonate powder manufacturing in India
Raviraj Minerals, based in Udaipur, Rajasthan, is one of India's leading calcium carbonate manufacturers. With ISO 9001:2015 certification, captive mineral sourcing, and exports to 25+ countries, we supply high-purity GCC and coated CaCO3 to top paint, plastic, rubber, and pharmaceutical manufacturers.
Uncoated (natural) calcium carbonate is hydrophilic and suited for water-based formulations and pharma. Coated calcium carbonate has a stearic acid surface treatment making it hydrophobic and organophilic — ideal for polymer compounding (PVC, PP, PE) as it allows higher filler loading without mechanical property loss.
Calcium carbonate prices in India range from ₹3,000 to ₹6,500 per tonne based on grade. Raviraj Minerals offers natural GCC from ₹4,750/tonne, fine grade at ₹5,500/tonne, and coated grade at ₹6,500/tonne. Contact us for bulk pricing.
GCC stands for Ground Calcium Carbonate — it is natural calcium carbonate mechanically ground from limestone or marble deposits. Raviraj Minerals produces GCC in various particle sizes (coarse to 10 micron fine) with purity up to 99% from high-grade Rajasthan mineral deposits.
Our Natural Calcium Carbonate Powder (99% CaCO3, heavy-metal-free) is suitable for use as a dietary calcium supplement in feed and pharmaceutical formulations. Contact us for a Certificate of Analysis (CoA) and full technical specifications.
