Ground Calcium Carbonate (GCC)

Kunal Calcium Limited is one of the largest manufacturer and exporter offering wide range of Ground Calcium Carbonates in India. The pertaining raw materials occurs naturally & used in the form of calcite Limestone.

Ground Calcium Carbonate is composed of naturally occurring high purity calcite ores containing CaCo3 as a primary component. The chosen Limestone must be washed, crushed, finely grinded and then classified precisely to obtain the exceptional and desirable quality of GCC as per the requirement of customers.

Ground Calcium Carbonate, commonly known as GCC in industrial applications, is widely used as a filler material. Ground Calcium Carbonate is also known with various name like RNCC, Natural Calcium Carbonate, Calcite Powder, Limestone Powder in different types of industries.
