Kaolin (Kaolinite) Processing
About Kaolin Clay. Kaolin, also known as kaolinite or ceramic clay, is a mineral primarily extracted from kaolinite ore.It is named after the hill in China (Kao-ling) from which it was mined for centuries. Kaolin contains primarily aluminum silicate and is often represented by the chemical formula Al 2 Si 2 O 5 (OH) 4.It is usually white or light gray and has a fine granular texture.
