Calcium Carbonate (CaCO₃) – Bulk Industrial

Calcium Carbonate (CaCO₃) is a white, odorless powder widely used as a filler, pH regulator, buffering agent, and mineral supplement. Found in rocks such as limestone, marble, and chalk, it is also produced synthetically for purity control. At Cavin Resource, we supply high-purity calcium carbonate in bulk quantities suitable for food, industrial, and pharmaceutical use.

Our calcium carbonate is processed using advanced milling and classification technologies to achieve consistent particle size, high brightness, and exceptional purity. We cater to wholesalers, manufacturers, and exporters with packaging customized to regional regulations and shipping needs.
