1. Product Overview
Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from high-purity
limestone or marble. It is mechanically ground into fine powder without changing its chemical
structure. GCC is widely used in various industrial applications due to its excellent physical and
chemical properties.

Quicklime (or calcium oxide or burnt lime) is obtained by calcining pure limestone at temperature above 9000C. This highly reactive product is essential to many industrial processes. Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
Application: Steel Making, FGD, Construction, Masonry & Mortars, Water Treatment, Chemical Processes, Mining Industry, sugar industry, Paper, Pulp and PCC, Remediation of Sludges and Wastes and Glass Manufacturing.
