Abstract. Kaolin is a claey sedimentary rock consisting of kaolinite and associated mainly with weathering crusts. Kaolin is widely used in the paper, ceramics, refractory, paint, rubber, cable, cosmetic and pharmaceutical industries. In addition, one of its modern directions is aluminum mining. The main large deposits of the world are located in Ukraine, the Czech Republic, and Great Britain and belong to the type of hydrothermal deposits. Primary and secondary kaolins from the Angren deposit are part of the raw material base of our republic.
