One of the most widely distributed and common clay minerals is Kaolinite. Kaolinite is a soft, earthy, usually white, mineral produced by the chemical weathering of aluminum silicate minerals like feldspar.
Kaolinite is composed of tiny plate-like particles that are stacked together in layers. These layers can slide over one another, giving kaolinite its characteristic plasticity and ability to be easily shaped when wet. Most kaolinite is mined as kaolin. The largest deposits are found in moist, warm climates. For example, in the United States the largest deposits are found across middle Georgia. Kaolinite is milled to obtain target particle sizes and surface areas which are key to its use in each different application.
