Get PriceApr 01, 2019· Clay (kaolin) is a white to yellowish or grayish fine powder. There are at least three different minerals, kaolinite, dickite, and nacrite, classified as kaolin. Kaolinite or china clay is whiter, less contaminated with extraneous minerals, and less plastic in water.
Get Priceing properties of kaolin clay contaminated by diesel oil. They carried out comprehensive tests on clay samples having oil contents of 4, 8, 12, 16, and 20% (by mass fraction). They found that as contamination degree of the kaolin clay increased, both the liquid and plastic limits decreased, but there was only a slight increase in plasticity index.
Get PriceOn the other hand, kaolin clay exhibited higher swelling with both acids than uncontaminated kaolin clay. However, compressibility marginally increased with both sulphuric acid and phosphoric acid. Formation of flocculant fabric along with mineral dissolution is responsible for deviations in compressibility behaviour of contaminated kaolin clay.
