Calcite Powder Manufacturers in India
As a calcite powder manufacturer based in Udaipur, Rajasthan, Vasundhara Micron processes natural calcite, a form of calcium carbonate, into white calcite powder with 92% to 99% whiteness in 500 to 1250 mesh. We mine, sort, grind and pack in house, so quality stays under our control from raw rock to sealed bag.
Our calcite powder goes into plastic, paint, rubber, PVC pipes, soap and detergent, paper and refractory products. If you need a dependable calcite powder manufacturer and supplier in India, you get consistent grades, laboratory tested batches and bulk pricing quoted against your exact requirement.
What Is Calcite Powder?
Calcite powder is finely ground natural calcium carbonate (CaCO₃). It combines high whiteness, high purity and free flow, which is why it is one of the most widely used industrial minerals.
It is used as a filler, extender and pigment, as an abrasive, as a soil conditioner and, in specially graded form, in pharmaceutical products. In factories it works mainly as a mineral filler that adds whiteness and bulk, improves consistency and lowers formulation cost.
Calcite powder comes in different mesh and micron sizes, and the right grade depends on the whiteness, purity and particle size your process needs. Vasundhara Micron, a calcite powder manufacturer in India, supplies grades from 500 to 1250 mesh for plastic, paint, rubber, paper and other industries.

Calcite Powder Manufacturer with Own Mines and In House Grinding
As a calcite powder manufacturer, we source raw material from our own mines and process it in our own grinding units. Grinding is done with pulverizers, material handling equipment, sieving machines and packing machines.
- Mining and sorting: raw calcite is sorted at the mine before it moves to grinding.
- Parameter check: the material is checked against our specifications before grinding starts.
- Grinding and sieving: the approved material is ground and sieved to the required mesh or micron size.
- Laboratory testing: each product is checked in our in house laboratory before shipment.
- Packing: pre packing and final packing are done as per customer requirements.
Calcite Powder vs Ground Calcium Carbonate (GCC)
Buyers often search for calcite powder, calcium carbonate powder and GCC as if they were different products. Calcite is the natural mineral form of calcium carbonate, and calcite powder is that mineral ground to a controlled particle size. Ground calcium carbonate (GCC) is the broader industry name for natural calcium carbonate that is ground, as opposed to precipitated calcium carbonate (PCC), which is made by a chemical process.
- Calcite powder / GCC: made by grinding and sieving natural material, which keeps cost low for high volume filler use.
- PCC: made by a chemical route, usually chosen where a very uniform particle shape is needed, and usually at a higher price.
If your specification asks for GCC or calcium carbonate filler, send it to us and we will match it to the closest calcite grade.
