Kaolin: A multifunctional mineral that boosts global industrial innovation

Kaolin is a natural white clay mineral. With its excellent whiteness, plasticity, chemical stability and adsorption performance, it has become a key raw material in industries such as ceramics, papermaking, coatings, rubber and medicine. With the global industrial upgrading and the growth of environmental protection demands, the market value of kaolin has been continuously rising. It is estimated that the global market size will reach 4.1 billion US dollars by 2025.

1. The core advantages of kaolin

• High whiteness & fine particles: Suitable for high-end ceramic and papermaking coatings, enhancing product gloss and printing quality.

• Excellent adsorption property: Modified kaolin can efficiently remove heavy metals (such as lead and mercury) from wastewater, contributing to the environmental protection industry.

• Biocompatibility: Medical-grade kaolin is safe and reliable for use as a drug carrier and hemostatic material.

• High-temperature resistance: Ideal choice for refractory materials and the aerospace industry.

2. The global market demand is strong

• Papermaking industry (accounting for 60% of global kaolin consumption) : Kaolin from Maoming, China, has replaced imported products and met the demand for high-end coated paper.

• Ceramic industry: The iron content of kaolin from Longyan, China, is extremely low (<0.3%), making it the preferred choice for high-end daily-use porcelain and electrical porcelain.

• Environmental protection and new materials: Modified kaolin is used in sewage treatment, lithium battery separators, and functional fillers, with huge market potential.

3. Why choose Chinese kaolin?

• Abundant resources: China leads the world in kaolin reserves, and Guangxi, Jiangxi, Guangdong and other places are rich in high-quality mineral sources.

• Technological innovation: Chinese enterprises such as Maoming Yinhua have mastered the high-concentration mineral processing method, with an extraction rate as high as 99%, and their products meet international standards.

• Cost advantage: Compared with imported products from the United States and Brazil, Chinese kaolin offers better cost performance and a more stable supply chain.
