With around 8 million metric tons mined and $1 billion in annual economic impact, kaolin is one of Georgia's largest natural resources and industries. In fact, Georgia is the leading clay-producing state in the nation. Primary applications of kaolin include paper-coating [glossy magazine pages, for instance], paint pigments, ceramics, and pharmaceuticals, especially …
Kaolin, although a rather homogeneous rock, and due to its dull outward appearance not high up on the agenda of mineral enthusiasts and rockhounds, has attracted mining and ceramic engineers involved in the manufacture of chinaware, and economic geologists dealing with non-metallic deposits.
The kaolinite-group minerals kaolinite, dickite, nacrite, halloysite including its metaform and their associates allophane and imogolite are phyllosilicates characterized by a rather simple chemical composition of Si, Al, O, and H. These elements contribute for the most part to the built-up of the continental earth crust, which down to a depth of approx. 1.5 km, …
