Zohdy Minerals Egypt is one of the leading producers of Ground Calcium Carbonate (GCC) in Saudi Arabia.
Calcium carbonate (CaCO₃) is a widely distributed chemical compound, making up about 4% of the Earth’s crust. It is the main component of limestone. Despite its abundance, not all types of limestone are suitable for GCC production due to the presence of impurities.

Calcium carbonate is one of the most useful and versatile materials known to mankind. Ground calcium carbonate is applied in numerous industries such as flooring, carpet, luxury vinyl tiles, stone plastic composites, paints, adhesives, paper, plastics, rubber, asphalt roofing, and even agriculture.

Raw Materials for Heavy Calcium Carbonate Production

• Limestone
  Formed by the deposition of calcium carbonate from lakes and seas, later compacted and solidified. It has a Mohs hardness below 3, making it a medium-hard material.
• Calcite
  A naturally occurring calcium carbonate mineral found abundantly across the globe. It appears in different crystal forms – granular, fibrous, stalactitic, or even earthy.
• Marble
  Primarily composed of calcium carbonate (over 50%). Known for its variety of colors and patterns, with hardness ranging from 2.5 to 5 on Mohs scale. Its beauty makes it highly valued in construction and decoration.
• Chalk
  A sedimentary form of calcium carbonate, derived from calcite. Formed over time from microscopic marine organisms (plankton) compacting at the bottom of oceans.

Key Applications of Ground Calcium Carbonate (GCC)

1. Rubber Industry
   • Used as a major filler in rubber formulations.
   • Improves tensile strength and tear resistance.
   • Reduces production costs as an economical filler.
   • Enhances surface appearance and thermal stability.
   • Applied in tires, seals, and gaskets.
