Calcite Powder
Calcite Powder, also known as Calcium Carbonate (CaCO₃), is a naturally occurring mineral obtained from high-purity limestone and marble. At Bigrock Mines & Minerals, we produce ultra-fine, high-whiteness Calcite Powder using precision grinding and classification technology.
Our Calcite Powder is appreciated for its chemical stability, low oil absorption, brightness (whiteness above 95%), and controlled particle size distribution, making it a preferred filler, extender, and functional additive across diverse industries.

Paints & Coatings Industry
This sector involves the production of decorative and industrial paints, emulsions, primers, and protective coatings. Calcite Powder is used here as a low-cost extender and whitening agent to enhance opacity, durability, and smooth finish.
Plastics & Polymers
This includes the manufacturing of plastic goods, films, pipes, profiles, containers, etc. Calcite improves strength, gloss, and processability, while reducing the usage of expensive resins like PVC or PE.
Rubber Manufacturing
This sector produces automotive tyres, rubber hoses, soles, seals, and industrial rubber components. Calcite acts as a functional filler to boost strength, elongation, and cost efficiency.
Paper & Pulp Industry
Engaged in the production of paper, board, packaging sheets, etc. Calcite is used for brightness and surface smoothness, while reducing pulp usage and improving ink absorption balance.
Building & Construction
This sector includes wall finishes, cement products, tile adhesives, plasters, etc. Calcite enhances shine, smoothness, and bond strength in surface coatings and masonry products.
Chemical Industry
A broad sector that produces inorganic and organic compounds. Calcite is used as a raw material or neutralizing agent, especially in calcium-based formulations, desulfurization, and industrial waste treatment.
Agriculture & Animal Feed
In farming, it is used to balance soil pH and improve soil structure. In animal nutrition, it provides essential calcium for bone health, metabolism, and shell development in poultry.
