Kaolin Processing Technology and Characteristics

The quality of kaolin is mainly reflected in three aspects of whiteness, purity and fineness. The higher the whiteness, the higher the purity, and the finer the particle size, the better the quality and the higher the price on the market. There are many factors that affect the quality of kaolin, mainly iron and titanium. According to the different properties of kaolin, its processing technology mainly includes kaolin beneficiation and purification, superfine grinding and surface modification.

Titanium Dioxide Production Process

Titanium dioxide (TiO2) has stable physical and chemical properties, excellent optical and electrical properties, and excellent pigment performance. TiO2 is the most versatile white pigment with the best application effect. This article will share the production process of titanium dioxide pigment.

Ground Calcium Carbonate Manufacturing Process

The main component of limestone is calcium carbonate, which is a sedimentary rock made of calcite or aragonite minerals. Mined limestone (calcite, limestone) is directly ground into powder to make ground calcium carbonate (GCC).

Recycling of Kaolin Tailings Waste

Kaolin will produce a large amount of tailings waste after ore beneficiation and recovery. Due to less recycling of kaolin tailings, as the tailings continue to accumulate, they will occupy a large amount of land, pollute water quality, cause vegetation damage and soil erosion, and even cause mudslides, which will seriously affect the ecological environment. Therefore, comprehensive utilization of kaolin tailings and recycling them can effectively prevent waste of resources and damage to the environment.
