Zinc occurs naturally as mineral zincite, but the major amount of zinc oxide for industrial and commercial applications is produced synthetically. The raw materials that are used for the production of zinc oxide are typically recycled byproducts. The commonly used raw materials are residual oxidic materials that are obtained from the galvanizing process or zinc bearing materials from mixed sources.

Calcium carbonate is mined from limestone reserves and further treated for superior quality. It is processed from naturally occurring high-purity calcite ores comprising CaCO₃as a chief component. it is further washed, ground, crushed, and customized as per products of desired quality and various grades.
