Kaolin is an aluminosilicate soft white mineral named after the hill in China (Kao-ling) from which it was mined for centuries. In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, and varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase.

When kaolinite undergoes percussive grinding, pronounced changes take place in its i.r. absorption spectrum even in the earliest stages of the grinding when the lattice is not yet destroyed. In this report, attention is directed to the change in the stretching bands of the hydroxyl ions. A remarkably rapid effect on the band of the intralayer hydroxyl ions has been observed …

The effect of dry grinding of kaolin minerals by a mechanical mortar was examined by x-ray, thermal, and electron microscopic methods. Base exchange capacity and apparent density were also measured. In the early stage of grinding, kaolin crystals cleave and fracture and then split into fine crystals which are considered unit crystallites. Such crystallites …

The kaolin is mined with diesel or electric shovels or draglines and loaded in trucks for transport to the processing plant or dropped directly from the dragline into a blunger. The blunger chews the kaolin into small lumps and mixes it with water and dispersing chemical to form a clay-water slip or slurry.

Kaolinite particles are characteristically thin, flat, and hexagonal in outline. The particles range in size from submicron to as much as 40 microns (equivalent spherical diameter). The kaolin is mined with diesel or electric shovels or draglines and loaded in trucks for transport to the processing plant or dropped directly from the dragline into a blunger.

Intensive dry grinding causes the structural deformation of kaolinite into an amorphous state with enhanced chemical reactivity. The degree of the activated state of kaolinite particles is mainly dependent on the grinding time and the activated particles easily react with NaOH to form zeolite Na-A and Na-X according to the degree of activation.
