Dolomite is a double carbonate mineral composed of calcium magnesium carbonate [CaMg(CO₃)₂]. Structurally, it is similar to calcite but with magnesium ions alternating with calcium ions in the crystal lattice. It typically contains approximately 30% CaO and 21% MgO. In its natural state, dolomite is usually white, gray, or flesh-colored, with a pearly or vitreous luster.

Calcium carbonate (CaCO₃) is one of the most significant and versatile inorganic compounds found in nature. It primarily originates from mineral ores such as calcite, marble, and limestone. It is also a major biological component found in animal bones and shells.

Compared to calcite, dolomite is slightly harder, with a Mohs hardness of 3.5–4. For HGM series grinding mills, this represents a material that is still highly processable but offers superior weather resistance and chemical stability. The presence of magnesium grants dolomite higher refractive indices and better resistance to acid than pure limestone. In industrial processing, dolomite is highly valued for its refractory properties and its ability to act as a potent fluxing agent. Its high MgO content makes it an indispensable source of magnesium for specialized glass and ceramic glazes, where it improves the durability and luster of the final product.

Ground Calcium Carbonate (GCC) is produced by the mechanical pulverization of natural minerals like limestone or marble. Since it involves no chemical transformation, it retains the mineral’s original stability but features an irregular, fragmented structure.

Key Properties: High density, low oil absorption, and excellent flowability.

Industrial Value: Used as a “functional filler” in plastics, rubber, and coatings. It increases volume and hardness while allowing high loading levels to significantly reduce production costs.

Precipitated Calcium Carbonate (PCC), or light calcium carbonate, is a synthetic compound produced through a chemical carbonation process. By calcining limestone and reacting it with CO₂, manufacturers can precisely control the particle morphology to create specific shapes like spindles, spheres, or needles.

Key Properties: Ultra-high whiteness, narrow particle size distribution, and high sedimentation volume.

Industrial Value: Its microporous structure and large specific surface area make it ideal for high-end paper, specialized paints, and pharmaceuticals requiring reinforcement and superior brightness.
