What 08.140 includes

  • Clays are complex, silico-aluminous minerals whose essential characteristics are plasticity, the ability to harden upon firing, and heat resistance. The term "various clays" includes what are known as clay soils, which are post-Pampean accumulations of clay associated with fine sand and silt, containing illite, montmorillonite, and kaolinite; these are used for the manufacture of common bricks and lightweight aggregates (expanded clays). The generic name "bentonites" refers to clays known in English literature as fuller earth.
  • Extraction of: - andalusite - complex silica-alumina clays - refractory, plastic, and bleaching clays, among others - bentonite - kaolin - kyanite - mullite - pyrophyllite - sillimanite - chamotte or dynamite - zeolite
