Secondary kaolins are widely used in the metallurgical industry (for the manufacture of refractory products), as well as in the ceramic, cement and other industries.
Kaolins must contain a minimum amount of calcium oxide, which provides them with appropriate refractoriness. Deposits are concentrated on the Ukrainian Crystalline Shield.
The State Balance of Mineral Resources of Ukraine includes 8 secondary kaolin deposits (Volodymyrivske, Kirovohradske, Murzynske, Novoselytske, Oboznivske, Yasnopolyanske, Balashivske and Polohivske).
To increase the mineral raw material base of secondary kaolins (especially higher grades), it is planned to conduct prospecting, prospecting and evaluation and exploration works in promising areas of the Ukrainian Crystalline Shield and its slopes.
