Kaolin is one of those minerals that is used in everyday life but is consistently overlooked, unlike higher profile mining products such as rare earths, lithium and gold. Yet, a closer look at what it is used for shows how indispensable kaolin actually is.

Kaolin. Kaolin from Lal Lal, Victoria (Scale: 13 cm) 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 ...

Once the kaolin is extracted, it is transported, usually via truck, to processing plants that are near the mine. Kaolin can be either dry- processed or wet-processed depending on its usage. Dry-processed kaolin mainly is used in the rubber industry. In dry processing, the raw kaolin is crushed into the desired size and dried using rotary dryers.

THE KAOLIN BELT. Kaolin is one of the many industrial minerals mined in Georgia today. The commercially mineable kaolin deposits are found in a relatively narrow "belt" along the Fall Line. The kaolin mining industry has located its processing facilities in the communities near the deposits, primarily in the nine rural counties between Macon ...

Kaolin is also used in medicines, paints and many other products, all of which are shipped around the world. At the end of the 20th century, kaolin was an $800 million business and Georgia's largest volume export. Mining companies have reclaimed and restored more than 80 percent of the land that has been stripped since 1969.

The kaolin mining industry has located its processing facilities in the communities near the deposits, primarily in the nine rural counties between Macon and Augusta. Highly technical equipment and processes are employed to transform the crude kaolin into high-quality products which are marketed around the world for a wide variety of applications.
