Kaolin is a hydrated aluminum silicate crystalline mineral (kaolinite, Al 2 (Si 2 O 5 ) (OH) 4 ). It was termed 'China clay' from its use in China, formed commonly from weathered granite or hydrothermal activity. It is typical of three main geological environments: (1) weathering profiles; (2) hydrothermal alterations; and (3) sedimentary ...

Mining companies have reclaimed and restored more than 80 percent of the land that has been stripped since 1969. About8 million metric tons of kaolin valued at more than $1 billions shipped annually from Georgia with most of it coming from the "white gold" belt in 13 counties along the fall line that girdles the mid-portion of the state.

Kaolinite was the dominant clay mineral in the kaolin deposits and occurrences in Africa with smectite and illite in major quantities, as well as a number of non-clay minerals commonly present in kaolins. Major applications of the kaolins included ceramics, bricks, earthenware, coating, paint, and functional filler.

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 feldspars. Kaolin deposits can be nearly pure kaolinite or may contain impurities that affect the characteristics of the clay.

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 and Augusta.
