Low iron dolomite is a high-purity form of the mineral dolomite, with very low iron content, and a chemical composition of calcium magnesium carbonate (CaMg(CO₃)₂). Due to its low iron levels, it has a bright white color and high brightness, making it ideal for applications where color quality and purity are important. It is widely used in industries such as glass, ceramics, paints, plastics, and rubber, where it helps improve strength, finish, and overall product quality. In the glass and ceramic industries, low iron dolomite prevents discoloration and enhances clarity, while in paints and plastics it acts as a cost-effective filler. Overall, it is valued for its high whiteness, low impurities, and versatility across various industrial applications.
Low iron dolomite is considered special mainly because of its very low iron (Fe) content, which gives it a high degree of whiteness and purity compared to normal dolomite. This makes it highly suitable for industries where even a slight discoloration can affect product quality, such as glass, ceramics, and paints. Its bright white color helps improve the appearance, brightness, and finish of final products. In addition, it offers good thermal stability, chemical resistance, and strength, making it useful as a reliable filler material in plastics and rubber. Because of these combined properties—purity, whiteness, and performance—low iron dolomite is treated as a premium-grade material for high-quality industrial applications.
