Calcium Carbonate (CaCO₃)

Mineral Description

Calcium Carbonate (CaCO₃) is a natural mineral found in rocks such as calcite, limestone and marble. It stands out for its high purity, white color, low abrasiveness and excellent chemical stability. It is one of the most widely used industrial minerals worldwide due to its versatility, availability and competitive cost.

Industrial Uses and Applications

Calcium carbonate is used across multiple industrial sectors:

  • Filler and mineral additive in plastics, PVC and rubber.
  • Production of paints, inks and coatings.
  • Paper industry as a whitening and opacity agent.
  • Agriculture: soil pH corrector.
  • Manufacturing of glass and ceramics.
  • Construction: cements, mortars, adhesives and prefabricated materials.
  • Food and pharmaceutical applications (specific grades).

Extraction and Origin

Calcium carbonate is obtained through the extraction of limestone in open-pit quarries. The standard process includes:

  • Drilling and controlled blasting.
  • Crushing and grinding of the rock.
  • Granulometric classification.
  • Micronization and purification for specialized industrial uses.

Main producing countries include China, India, Spain, Turkey, Vietnam and Egypt.
