Answer:
Georgia is the world's leading producer of Kaolin (china clay).
Explanation:
Kaolin or china clay contains the mineral kaolinite mainly. It also contains varying amounts of other minerals like muscovite, feldspar, quartz, etc. In order to prepare it for commercial use, the clay in its natural form is then chemically treated and washed with water to remove the other minerals.
Kaolin is extensively used in the ceramic industry and the paper-coating industry. The high fusion temperature and white burning characteristics are used in the ceramic industry for the manufacture of chinaware, porcelain, and refractories. In the paper-coating industry, the kaolin is mixed with the cellulose fiber in the paper sheet. This gives the paper its color, opacity, and printability. It is also used as a pigment additive in paints, as a filler in plastic and rubber compounds, and in pharmaceuticals.
