Abstract

The material composition of kaolin raw materials with the content of Al₂O₃ – 17,21; SiO₂ – 66,27; Fe₂O₃ – 0,51; TiO₂ 0,574 was studied. The main valuable minerals are kaolinite, halloysite, muscovite, quartz, rare marks of tourmaline, ilmenite. Particle size analysis of kaolin raw materials shows that the largest mass is represented by the size class (- 0,05+0 mm) – 43,08 %. 79,74 % of alumina with its content of 32,0 % is in the size class (- 0,05+0 mm), and it can be used as a raw material for further processing into alumina or as a universal filler for production of paper, rubber, cable, plastic and perfumery products.
