The Calcium Carbonate Manufacturing Process. Natural mineral sources are necessary to make commercially usable calcium carbonate. Manufacturing processes are used to improve specific properties and reduce the size of particles within the material. Calcium carbonate is mined from open pits or underground, then drilled, blasted, and crushed.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

The two crystal forms are relatively soft. Calcite has a Mohs hardness of three, while that of aragonite is slightly higher at 3.5–4. Calcite usually occurs as rhombohedral crystals, while aragonite frequently occurs in acicular or needlelike form. Vaterite is a relatively rare crystal form and not met with as a polymer additive.

Namely, nano-sized grains are produced by physical processes such as grinding. In the top-down approach there are two options such as wet and dry grinding. In this study, dry grinding was preferred to eliminate the cost of drying. The general flow diagram of the nano-calcite fabrication using an industrial scale ball mill is given in Figure 1.
