| Abstract: |
Kaolin and related clay deposits of Thailand are located in 6 main provinces, Lampang and Uttaradit in the North, Prachinburi in the Central and Nakorn Si Thammarat-Surat Thani, Ranong and Narathiwat in the South. These deposits represent the major mode of occurrences of kaolin that known to exist in the world. They are hydrothermal, residual and sedimentary deposits. The main sources are granitic and rhyolitic rocks. The major uses of Thai kaolin are mainly in ceramics, rubber, paints and paper. The annual output of commercial kaolin exceeds the peak at 45,000 metric tons in 1979. Common clays have been mined throughout the country mainly for the manufacture of construction bricks and pottery, and for a lesser extent in tiles. Shales are solely used for cement manufacturing.
