2 Properties of raw ore Muscovite-type kaolin raw ore contains 18.78% (mass fraction) Al2O3, 71.69% SiO2, and 0.72% Fe2O3. The results of microscope observation present that the main clay minerals are halloysite (7 Å) and minor illite in the kaolin (Fig.1). The halloysite is of needle-like crystal structure that is made of extremely fine hollow

The term kaolin is typically used for clayey material that is low in iron content and is white or nearly white and composed of minerals of the kaolin group. The kaolin-forming clays are all hydrous aluminium silicates, essentially kaolinite [Al 2 (Si 2 O 5)(OH) 4], that are formed by the decomposition of other aluminous minerals, especially ...

There are abundant kaolin reserves in China, however the high-grade kaolin and its refined products will remain one of the bulk commodities to be imported due to the low grade of its raw ore (Ye et al., 2014). Therefore, there is a strong spatial variability in kaolin's global supply and demand.

The ore is removed using heavy machinery, such as bulldozers, draglines, or power shovels. Blunging: The mined kaolin ore is then transported to a processing plant, which is crushed and mixed with water to form a slurry. This process is called blunging, which helps to disperse the particles and produce a homogenous mixture.

Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral's whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.
