Abstract: Kaolin clay from Deopani deposit of Assam contains high amount of iron. Kaolinite particles, characterized by SEMEDX, are pseudohexagonal and arranged in face-to-face pattern. Clay particles are coated with iron- and titanium-bearing minerals, which can be separated by wet high intensity magnetic separator Titaniferrous impurities present as coatings on kaolinite particles are difficult to remove by oxalic acid treatment.
