Problem statement: The Barat-Algaof kaolin deposits are characterized and evaluated for its potentials as an industrial raw material. Approach: This research studied the total mineralogical composition of the kaolin deposit, chemical and physical properties as well as intercalation of kaolinite by urea. Using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Laser particle size, Centrifuge, data from UK (England) kaolin standard and Hinckley crystallinity index were also compared. Three samples of kaolin were treated by urea intercalation. Results: Results showed high content of kaolinite after the removal of non-kaolin minerals; the major elements percentages are almost similar to that of U.K kaolin and the low value of whiteness refers to the presence of iron containing minerals in the samples. Moreover, a well crystallinity index of kaolin was obtained. Intercalation of urea into kaolinite expands the basal space and the reduction of particle size of kaolinite after intercalation is evident in the Scanning Electron Microscopy. Conclusion: we concluded that kaolinite of the study area can be used as raw materials for industrial purposes.
